Definitions
- the present invention relates to a vacuum cleaner having a filter for collecting dust and debris.
- a conventional vacuum cleaner has known.
- the vacuum cleaner includes a first filter (a first dust and debris separator) for separating dust and debris from the air that is taken in with the air in a dust collecting room, a pleat filter (a second dust and debris separator) for separating from the air the thin dust that passed the first filter, a dust dumping member (a dust removal unit) that can move so as to continuously strike a lot of protrusions of the pleat filter, a cord reel for winding a power cord, and an interlocking unit for transmitting a rotation of the cord reel to the dust dumping member.
- a first filter a first dust and debris separator
- a pleat filter a second dust and debris separator

- the dust dumping member reciprocates by linking with the vertical motion of the handle.
- the dust dumping member and the filter produce a first load therebetween when the handle is moved upward by a manual operation; the dust dumping member and the filter produce a second load therebetween when the handle is moved down to the storing position by the storage spring; and the second load is determined to be smaller than the first load.
- the filter is a pleat filter in which a multiplicity of folds having crests and troughs extending in the vertical direction are arranged in the horizontal direction; and the dust dumping member is provided to be able to reciprocate in the direction in which the folds are arranged, by linking with the vertical motion of the handle; and further comprises a first guide provided in the dust dumping member for going by linking with the motion of the handle when the handle is moved upward by a manual operation and for sequentially striking the folds; and a second guide provided in the dust dumping member for returning by linking with the motion of the handle when the handle is moved downward by the storage spring and for sequentially striking the folds weaker than the first guide.
- the filter is a pleat filter in which a multiplicity of folds having crests and troughs extending in the vertical direction are arranged in the horizontal direction; the dust dumping member is provided to be able to reciprocate in the direction in which the folds are arranged, by linking with the vertical motion of the handle; and the dust dumping member is provided to return by linking with the handle when the handle is moved downward by the storage spring, and to be rotatable in the direction opposite to the returning direction.

- the dust removing unit 300 includes a pair of dust dumping members 304 and 304 as a dust removing unit mounted on the left and right ends of a slider 302.
- the dust dumping member 304 includes a dust damping unit 305, an installation boss 306 integrally attached to a base of the dust damping unit 305, and legs 307 and 308 extending parallel, branched left and right of the installation boss 306 from the base of the dust damping unit 305.
- the dust dumping member 304 is mounted horizontally rotatably on both ends of the slider 302 through the installation boss 306. As shown in Figure 14 , support walls 309 and 310 are formed on the slider 302 that are located between legs 307 and 308. The dust damping unit 305 protrudes upstream of (in front of) the slider 302.
- a coil spring (an elastic member) 311 is disposed between the leg 308 and the support wall 309.
- the coil spring 311 is energized so that the leg 307 can contact with an outer surface of the support wall 309. While the leg 307 contacts with the outer surface of the support wall 309, the dust dumping unit 305 is almost vertical with respect to the slider 302.
- the dust dumping unit 305 is designed to reciprocate as one unit together with the slider 302 in the A1 and A2 directions designated by the arrows.
- the side of the dust dumping unit 305 in going one way constitutes a first engagement portion 305a that is almost vertical with respect to the slider 302 while the leg 307 touches the outer surface of the support wall 309.
- the side of the dust dumping unit 305 in returning constitutes a second engagement unit 305b that is inclined with respect to the slider 302 while the leg 307 touches the outer surface of the support wall 309.
- the dust removing unit 300 includes a power transmission unit 300A that transforms a vertical motion of the handle 200 to a horizontal motion of the slider 302.
- the power transmission unit 300A is rotatably attached to the front wall, and contains a pinion 312 for engaging with the rack 303, a pinion 313 fixed on a rotational axis 312a (see Figure 8A ) for the pinion 312, a gear 314 for engaging the pinion 313 and rotatably attached to the back of the front wall 31, and a pinion 315 integrally provided with the gear 314.
- the power transmission unit 300A includes a rack 316 for engaging with the pinion 315 and held at the back of the front wall 31 to be vertically movable, a protrusion 317 mounted on the rack 316, and a link 318 placed between a portion close to the base of the leg 200b of the handle 200 and the protrusion 317.
- the lower end (one end) of the link 318 is mounted on the protrusion 317 to be rotatable back and forth, while the upper end (the other end) of the link 318 is mounted on the portion close to the base of the leg 200b of the handle 200 by a link removing unit B 1 to be rotatable back and forth.
- the link removing unit B1 consists of an oval hole 318a and a support axis 318b.
- the oval hole 318a is formed at the upper end of the link 318.
- the support axis 318b is inserted into the oval hole 318a and is mounted on the portion close to the base of the leg 200b. Therefore, the upper end of the link 318 is supported by the support axis 318b so that the upper end can be rotated about the leg 200b.
- the rack 316 can move vertically in a predetermined range by the arrangement of a pair of upper and lower guide slits 319 and 319 formed in the guide portion 317a and a pair of protrusions 320 and 320 that are ejected at the back of the front wall 31 and inserted into the guide slits 319 and 319. As shown in Figure 8A , at a position in which the handle 200 lies down, since the upper end of the guide slits 319 and 319 comes in contact with the protrusions 320 and 320, the rack 316 is prevented from moving downward.
- a spring storing space 321 is provided that has a spring receiving wall 321a at the upper end.
- the spring storing space 321 includes a coil spring (a handle storage spring) 323 disposed between the spring receiving projection 322 and the spring receiving wall 321a.
- a brake unit 324 is arranged between the lower portion of the leg 200a of the handle 200 and the brake drum 34a in the side of the cord reel 34.
- the brake unit 324 contains a brake release lever 325 rotatably mounted about a support axis 325a in the housing 30, a roll supporting unit 326 having a inverse U shape and disposed together with the brake release lever 325, an oval hole 327 provided on side plates 326a and 326a of the roll supporting unit 326 and extending inclined in the back and forth direction, a rubber roll 328 placed between the side plates 326a and 326a, and an axis portion provided in the rubber roll 328 and inserted into the oval hole 327 to be movable in the back and forth direction.
- a spring force of a spiral spring (not shown), which rotates the cord reel 34 in the direction in which the power cord 34b is wound, prevents the cord reel 34 from rotating, with the rubber roll 328 pressed by the brake drum 34a.
- the axial portion 329 of the rubber roll (brake roll) 328 moves to the front of the oval hole 327. Accordingly, since the pressure to the brake drum 34a by the rubber roll 328 is released, the brake is also released.
- the leg 200a of the handle 200 only touches the upper end of the brake release lever 325, and at the same time the supporting axis 318b is located at the upper end of the oval hole 318a, which enables the handle 200 to be further pressed downward. Therefore, even if the handle 200 is further pressed downward from the handle storing position, the brake release lever 325 is pressed down at the leg 200a of the handle 200, and the brake of the cord reel 34 by the rubber roll 328 is released, the slider 302 and the dust dumping member never move. As a result of this, it can be prevented beforehand that release of the brake by the handle operation damages the slider 302 and the dust dumping member 304.
- the dust collecting container 50 includes a circular wind passage unit 51 (see Figures 4 and 5 ), a dust collector 60 (a first dust collector) as a first dust collecting room formed under the circular wind passage unit 51, a negative pressure room 70 formed at the back of the dust collector 60, and a bottom lid 80.
- the circular wind passage unit 51 includes a circular wind passage 53 having an arc shape around the circumference of a dust and debris separator (a first dust and debris separator) 52 placed in the center.
- An end aperture located at the end of the circular wind passage 53, as shown in Figure 3 is connected to the connection aperture 23 of the duct 22 of the lid 40.
- the circular wind passage 53 communicates with the dust collector 60 through a rear end aperture 55.
- An aperture 57 is formed that communicates with the negative pressure room 70 at the bottom in the circular wind passage 53.
- the aperture 57 is equipped with a net filter F2.
- the dust and debris separator 52 is composed of a net filter F1 formed in a shape of a truncated cone and has an aperture 56 at the bottom. The dust and debris separator 52 communicates with the negative pressure room 70 through the aperture 56.
- An aperture 62 for communicating with the negative pressure room 70 is formed at a separation wall 61 at the back of the dust collector 60.
- a communication hole (communication aperture) 63 is formed at a lower wall 61A of the separation wall 61. That is, the communication hole 63 is made under the aperture 62.
- the aperture 62 is provided with a net filter F3.
- a frame 71 for removably fitting a pleat filter 100 of Figure 3 is formed at the back (right side in Figure 5 ) of the negative pressure room 70.
- a rear end aperture 72 of the frame 71 is connected to a front aperture (not shown) of the housing 30 shown in Figure 3 .
- the pleat filter 100 as shown in Figures 14 and 15 , consists of crests and troughs extending vertically, and has a lot of folds 100a arranged horizontally. As shown in Figure 14 , the end of the dust dumping unit 305 provided at the dust dumping member 304 engages with the back of the pleat filter 100 (downstream of the air flow).
- a lower back wall 73 is formed in the lower portion of the frame 71.
- a space enclosed by the lower back wall 73 and the lower wall 61A of the separation wall 61 of the dust collector 60 and the bottom lid 80 constitutes a thin dust collector (a second dust) 74.
- the thin dust collector 74 communicates with the dust collector 60 through the communication hole 63 of the separation wall 61.
- a lower frame wall 71A of the frame 71 and the lower wall 61A of the separation wall 61 constitutes an introduction aperture 75.
- an open-close plate (an open-close lid) 76 for closing the introduction aperture 75 is axially supported at the lower portion of the separation wall 61 of the dust collector 60.
- the open-close plate 76 is rotably around one end.
- the open-close plate 76 closes the communication hole 63 of the separation wall 61 through its weight to open the introduction aperture 75 of the thin dust collector 74.
- the open-close plate 76 rotates to close the introduction aperture 75 (see Figure 9 ).
- a bottom lid 80 is supposed to rotate clockwise about an axis 81, as shown in Figure 3 .
- the rotation opens the bottom of the dust collector 60 and the thin dust collector 74 to dump the dust piled up in the dust collector 60 and the thin dust collector 74.
- the dust collecting container 50 is placed on the bottom 35 of the housing 30 and the lid 40 is closed. Then, as shown in Figure 1 , one end of the dust collecting hose 21 is connected to the hose connecting port 21 of the lid 40.

- Operating the switch S of the handle grip 13A drives the electric blower 33.
- Driving the electric blower 33 makes the pressure of the negative room 70 of the dust collecting container 50 and the dust collector 60 negative.
- the negative pressure affects a intake room (not shown) of the intake port member through the circular wind passage 53, the dust collecting hose 12, the handle grip 13, and the extension duct (extension pipe) 14.
- dust and debris on a cleaning surface are taken in together with the air to the intake room (not shown) of the intake port member 15.
- the dust and debris taken in to the intake room (not shown) of the intake port member 15 are taken in with the air to the extension duct (extension pipe) 14, the handle grip 13, and the dust collecting hose 12, and the circular wind passage 53 of the dust collecting container 50.
- the air that has flown in the negative pressure room 70 passes through a pleat filter 100 to be absorbed in the electric blower 33. After the air cools the electric blower 33, it is discharged out of an exit (not shown) of the housing 30 to the outside. On this occasion, the thin dust flown in the negative pressure room 70 is captured by the pleat filter 100.
- the operation when the handle 100 is stood up is explained below. With respect to the vacuum cleaner, when an operator holds the handle 200 and lift the body 20, the handle 100 stands up from a storing position (position P of Figure 16 ) of Figures 7 and 8 to a using position (position Q of Figure 16 ) of Figures 9 and 10 . According to this, the rack 316 that interlinks with the handle 200 is pulled upward as shown in Figure 10 through the link 318.
- the pinion 315 can be rotated, whose rotation is transmitted to the rack 303 through the gear 314, the pinion 313, and the pinion 313.
- the slider 302 having the rack 303 is moved (gone one way) in the direction of an arrow A1 from a left position (position P of Figure 17 ) of Figure 7 to a right position (position Q of Figure 17 ) of Figure 9 .
- the dust dumping member 304 of the slider 302 of Figures 13 and 14 is moved (gone one way) in the direction of an arrow A1 together with the slider 302.
- the first engagement portion 305a provided on the dust dumping unit 305 of the dust dumping member 304 engages with, and climbs over, the fold 100a of the pleat filter, as shown in Figure 14 .
- the fold 100a is repelled strongly by the first engagement unit 305a to vibrate the pleat filter 100.
- This movement is performed sequentially with respect to a lot of folds 100a, by which the thin dust attached to the upstream surface of the pleat filter 100 is dropped to be captured in the thin dust collector 74.
- the operation when the handle 100 is laid down is discussed hereinbelow.
- the handle 200 When the body 20 is moved to a cleaning surface and the handle is released, the handle 200 is lowered from a using position (position Q of Figure 16 ) of Figures 9 and 10 to a storing position (position P of Figure 16 ) of Figures 7 , 8A and 8B by a force of the coil spring 323.
- the pinion 315 is rotated, whose rotation is transferred to the rack 303 through the gear 314, the pinion 313, and the pinion 312.
- the slider 302 having the rack 303 is moved (returned) in the direction of the arrow A2 from a right position (position Q of Figure 17 ) of Figure 9 to a left position (position P of Figure 17 ) of Figure 7 .
- the dust dumping member 304 of the slider 302 in Figures 13 and 14 is moved (returned) together with the slider 302 in the direction of the arrow A2.
- the dust dumping member 304 rotates in the direction of the arrow A3 around the installation boss 306 until the leg 308 hits the supporting wall 310. This allows the second engagement portion 305b to repel weakly than the first engagement portion 305a to vibrate the pleat filter100.
- This movement is performed sequentially with respect to a lot of folds 100a, so that the thin dust attached to the upstream surface of the pleat filter100 is dumped to be collected in the thin dust collector 74.
- Winding operation of the power cord 34b is explained hereinafter. Based on this operation, because a lot of folds 100a of the pleat filter 100 is always repelled by at least one of the two dust dumping members 304 and 304, the dust and debris attached to the pleat filter100 is dumped.
- the leg 200a of the handle 200 contacts with the upper end of the brake release lever 325 (position P of Figure 16 ), as shown in Figures 11 and 12 , by the weight of the handle 200 itself.
- the supporting axis 318b of the link 318 is located in the upper end in the vertical direction of the oval hole 318a, the handle can be lowered further.
- the handle 200 is further pressed down to lower the brake release lever 325 by the leg 200a of the handle 200.
- the rubber roll 328 is lifted upward away from the brake drum 34a, the brake of the cord reel 34 is released by the rubber roll 328.
- the power cord 34b is wound around the cord reel 34 by a force of a spiral spring (not shown).
- the dust dumping member can be driven with a simple structure.
- the dust of the pleat filter 100 is removed.
- a paper pack filter can be employed instead.
- the dust of the paper pack filter can removed by vibrating the paper pack filter, using a member that moves linking with the vertical motion of the handle.
- the handle is provided to be isolated, so that the grip is designed to move vertically.
- the handle may be attached to the vacuum cleaner body so that it moves simply vertically.
- Reciprocation motion by the dust dumping member enables the dust of the filter to be dumped effectively.
- the dust dumping member can go one way making use of a repelling force of gravity of the vacuum cleaner body when the handle is lifted, the first load produced between the dust dumping member and the filter can be made larger when the handle is lifted upward by a manual operation. Consequently, a larger vibrating force can be applied to the filter (100) from the dust dumping member (304).
- the handle is returned to the storage position by means of a spring force of the storage spring (coil spring 323)
- the second load produced between the dust dumping member and the filter is made smaller than the first load when the handle is moved downward to the storage position by the storage spring. Because only the spring force of the storage spring (coil spring 323) can return the dust dumping member, a vibration can be applied to the filter from the dust dumping member to remove the dust even if the storage spring (coil spring 323) has a weak spring force.
- the C surface or R surface other than the inclined surface can be used as the second guide (second engagement portion 305b).
- the dust dumping member when it returns owing to a spring force of the storage spring (coil spring 323), it may rotate in the direction opposite to the movement direction (returning direction) or do not have to rotate.

Thecord reel 34 is rotatably attached to thehousing 30 by ahorizontal axis 34a ofFigure 11 and is provided to be able to wind apower cord 34b ofFigure 11 by a spiral spring (not shown). Since this structure is well known, a detailed explanation thereof will be omitted. - A plate-
like bottom 35 is provided in front of the housing 30 (a left side inFigure 3 ). Thedust collecting container 50 is removably placed on thebottom 35. When thelid 40 is closed, thelid 40 and thebottom 35 sandwich thedust collecting container 50 to fix it. - As shown in
Figure 3 , thelid 40 contains aduct 22 whose end is thehose connection port 21. The back end of theduct 22 is aconnection port 23. - As shown in
Figure 2 , afront wall 31 is placed at aback portion 30A of thehousing 30. In thefront wall 31, as shown inFigures 7-10 , afront aperture 201 is formed. Thefront aperture 201 communicates with anintake port 33A of theelectrical blower 33 through a communication wind passage (not shown). At thefront wall 31, as shown inFigure 7 ,side walls dust removing unit 300 is provided. - The
dust removing unit 300, as shown inFigure 7 , includes a pair ofaxial guide rails slider 302 that is held to be able to voluntarily move left and right on the guide rails. The guide rails 301 and 301, both ends of which are fixed at theside walls slider 302 facing thefront wall 31, as shown inFigures 7 and13 , arack 303 is arranged that has a lot of teeth disposed in the horizontal direction. - The
dust removing unit 300, as shown inFigure 13 , includes a pair ofdust dumping members slider 302. Thedust dumping member 304 includes adust damping unit 305, aninstallation boss 306 integrally attached to a base of thedust damping unit 305, andlegs installation boss 306 from the base of thedust damping unit 305. - The
dust dumping member 304 is mounted horizontally rotatably on both ends of theslider 302 through theinstallation boss 306. As shown inFigure 14 ,support walls slider 302 that are located betweenlegs dust damping unit 305 protrudes upstream of (in front of) theslider 302. - A coil spring (an elastic member) 311 is disposed between the
leg 308 and thesupport wall 309. Thecoil spring 311 is energized so that theleg 307 can contact with an outer surface of thesupport wall 309. While theleg 307 contacts with the outer surface of thesupport wall 309, thedust dumping unit 305 is almost vertical with respect to theslider 302. - As shown in
Figure 13 , thedust dumping unit 305 is designed to reciprocate as one unit together with theslider 302 in the A1 and A2 directions designated by the arrows. The side of thedust dumping unit 305 in going one way constitutes afirst engagement portion 305a that is almost vertical with respect to theslider 302 while theleg 307 touches the outer surface of thesupport wall 309. In contrast, the side of thedust dumping unit 305 in returning constitutes asecond engagement unit 305b that is inclined with respect to theslider 302 while theleg 307 touches the outer surface of thesupport wall 309. - The
dust removing unit 300 includes apower transmission unit 300A that transforms a vertical motion of thehandle 200 to a horizontal motion of theslider 302. - The
power transmission unit 300A, as shown inFigure 7 , is rotatably attached to the front wall, and contains apinion 312 for engaging with therack 303, apinion 313 fixed on arotational axis 312a (seeFigure 8A ) for thepinion 312, agear 314 for engaging thepinion 313 and rotatably attached to the back of thefront wall 31, and apinion 315 integrally provided with thegear 314. - As shown in
Figure 8A , thepower transmission unit 300A includes arack 316 for engaging with thepinion 315 and held at the back of thefront wall 31 to be vertically movable, aprotrusion 317 mounted on therack 316, and alink 318 placed between a portion close to the base of theleg 200b of thehandle 200 and theprotrusion 317. - The lower end (one end) of the
link 318 is mounted on theprotrusion 317 to be rotatable back and forth, while the upper end (the other end) of thelink 318 is mounted on the portion close to the base of theleg 200b of thehandle 200 by a link removing unit B 1 to be rotatable back and forth. - As shown in
Figure 8 B , the link removing unit B1 consists of anoval hole 318a and asupport axis 318b. Theoval hole 318a is formed at the upper end of thelink 318. Thesupport axis 318b is inserted into theoval hole 318a and is mounted on the portion close to the base of theleg 200b. Therefore, the upper end of thelink 318 is supported by thesupport axis 318b so that the upper end can be rotated about theleg 200b. - The
rack 316 can move vertically in a predetermined range by the arrangement of a pair of upper and lower guide slits 319 and 319 formed in theguide portion 317a and a pair ofprotrusions front wall 31 and inserted into the guide slits 319 and 319. As shown inFigure 8A , at a position in which thehandle 200 lies down, since the upper end of the guide slits 319 and 319 comes in contact with theprotrusions rack 316 is prevented from moving downward. - At the
front wall 31, aspring storing space 321 is provided that has aspring receiving wall 321a at the upper end. Thespring storing space 321, which is close to theguide portion 317a, extends vertically and are open at the back. In thespring storing space 321, aspring receiving projection 322, which is integrally provided at the lower end of theguide portion 317a, is arranged. Thespring storing space 321 includes a coil spring (a handle storage spring) 323 disposed between thespring receiving projection 322 and thespring receiving wall 321a. - As shown in
Figure 11 , between the lower portion of theleg 200a of thehandle 200 and thebrake drum 34a in the side of thecord reel 34, abrake unit 324 is arranged. Thebrake unit 324 contains abrake release lever 325 rotatably mounted about asupport axis 325a in thehousing 30, aroll supporting unit 326 having a inverse U shape and disposed together with thebrake release lever 325, anoval hole 327 provided onside plates roll supporting unit 326 and extending inclined in the back and forth direction, arubber roll 328 placed between theside plates rubber roll 328 and inserted into theoval hole 327 to be movable in the back and forth direction. - Where the
axial portion 329 of the rubber roll (brake roll) 328 has moved to the back end of theoval hole 327, a spring force of a spiral spring (not shown), which rotates thecord reel 34 in the direction in which thepower cord 34b is wound, prevents thecord reel 34 from rotating, with therubber roll 328 pressed by thebrake drum 34a. When thepower cord 34b is pulled out from thecord reel 34, theaxial portion 329 of the rubber roll (brake roll) 328 moves to the front of theoval hole 327. Accordingly, since the pressure to thebrake drum 34a by therubber roll 328 is released, the brake is also released. - Pressing downward the
release lever 325 by the brake separates therubber roll 328 from thebrake drum 34a, which releases the brake of thecord reel 34. Because thecord reel 34 is rotated by the spring force of the spiral spring (not shown), thepower cord 34b is wound on thecord reel 34. The well-known structure can be employed for thebrake unit 324. - When the
handle 200 is stored in the coil spring (the handle storing spring) 323 in the handle storing unit 30b and the upper ends of the guide slits 319 and 319 come in contact with theguide protrusions leg 200a of thehandle 200 only touches the upper end of thebrake release lever 325, and at the same time the supportingaxis 318b is located at the upper end of theoval hole 318a, which enables thehandle 200 to be further pressed downward. Therefore, even if thehandle 200 is further pressed downward from the handle storing position, thebrake release lever 325 is pressed down at theleg 200a of thehandle 200, and the brake of thecord reel 34 by therubber roll 328 is released, theslider 302 and the dust dumping member never move.
As a result of this, it can be prevented beforehand that release of the brake by the handle operation damages theslider 302 and thedust dumping member 304. - As shown in
Figure 3 , thedust collecting container 50 includes a circular wind passage unit 51 (seeFigures 4 and5 ), a dust collector 60 (a first dust collector) as a first dust collecting room formed under the circularwind passage unit 51, anegative pressure room 70 formed at the back of thedust collector 60, and abottom lid 80. - The circular
wind passage unit 51, as shown inFigure 6 , includes acircular wind passage 53 having an arc shape around the circumference of a dust and debris separator (a first dust and debris separator) 52 placed in the center. An end aperture located at the end of thecircular wind passage 53, as shown inFigure 3 , is connected to theconnection aperture 23 of theduct 22 of thelid 40. Thecircular wind passage 53 communicates with thedust collector 60 through arear end aperture 55. - An
aperture 57 is formed that communicates with thenegative pressure room 70 at the bottom in thecircular wind passage 53. Theaperture 57 is equipped with a net filter F2. The dust anddebris separator 52 is composed of a net filter F1 formed in a shape of a truncated cone and has anaperture 56 at the bottom. The dust anddebris separator 52 communicates with thenegative pressure room 70 through theaperture 56. - An
aperture 62 for communicating with thenegative pressure room 70 is formed at aseparation wall 61 at the back of thedust collector 60. A communication hole (communication aperture) 63 is formed at alower wall 61A of theseparation wall 61. That is, thecommunication hole 63 is made under theaperture 62. Theaperture 62 is provided with a net filter F3. - A
frame 71 for removably fitting apleat filter 100 ofFigure 3 is formed at the back (right side inFigure 5 ) of thenegative pressure room 70. Arear end aperture 72 of theframe 71 is connected to a front aperture (not shown) of thehousing 30 shown inFigure 3 . - The
pleat filter 100, as shown inFigures 14 and 15 , consists of crests and troughs extending vertically, and has a lot offolds 100a arranged horizontally. As shown inFigure 14 , the end of thedust dumping unit 305 provided at thedust dumping member 304 engages with the back of the pleat filter 100 (downstream of the air flow). - A
lower back wall 73 is formed in the lower portion of theframe 71. A space enclosed by thelower back wall 73 and thelower wall 61A of theseparation wall 61 of thedust collector 60 and thebottom lid 80 constitutes a thin dust collector (a second dust) 74. Thethin dust collector 74 communicates with thedust collector 60 through thecommunication hole 63 of theseparation wall 61. A lower frame wall 71A of theframe 71 and thelower wall 61A of theseparation wall 61 constitutes anintroduction aperture 75. - One end (upper portion in
Figure 3 ) of an open-close plate (an open-close lid) 76 for closing theintroduction aperture 75 is axially supported at the lower portion of theseparation wall 61 of thedust collector 60. The open-close plate 76 is rotably around one end. When theelectric blower 33 is not driven, the open-close plate 76 closes thecommunication hole 63 of theseparation wall 61 through its weight to open theintroduction aperture 75 of thethin dust collector 74. When theelectric blower 33 drives thenegative pressure room 70 negative, the open-close plate 76 rotates to close the introduction aperture 75 (seeFigure 9 ). - A
bottom lid 80 is supposed to rotate clockwise about anaxis 81, as shown inFigure 3 . The rotation opens the bottom of thedust collector 60 and thethin dust collector 74 to dump the dust piled up in thedust collector 60 and thethin dust collector 74.
Next, the operation of the vacuum cleaner having the above structure will be described. - As shown in
Figure 2 , thedust collecting container 50 is placed on the bottom 35 of thehousing 30 and thelid 40 is closed. Then, as shown inFigure 1 , one end of thedust collecting hose 21 is connected to thehose connecting port 21 of thelid 40. - As shown in
Figure 3 , anend aperture 54 of thedust collecting container 50 is connected to theduct 22 of the connection aperture, so that thedust collecting hose 12 is connected to the circularwind passage unit 51 of thedust collecting container 50. - Operating the switch S of the
handle grip 13A drives theelectric blower 33. Driving theelectric blower 33 makes the pressure of thenegative room 70 of thedust collecting container 50 and thedust collector 60 negative. The negative pressure affects a intake room (not shown) of the intake port member through thecircular wind passage 53, thedust collecting hose 12, thehandle grip 13, and the extension duct (extension pipe) 14. - By means of the negative pressure, dust and debris on a cleaning surface (not shown) are taken in together with the air to the intake room (not shown) of the
intake port member 15. The dust and debris taken in to the intake room (not shown) of theintake port member 15 are taken in with the air to the extension duct (extension pipe) 14, thehandle grip 13, and thedust collecting hose 12, and thecircular wind passage 53 of thedust collecting container 50. - Part of both the air and the thin dust absorbed into the
circular wind passage 53 flows in thenegative pressure room 70 through the net filter F1 and the net filter F2. On the other hand, the larger and heavier of the dust and debris and part of the thin dust taken in together with the air in the circular wind passage 53flows along thecircular wind passage 53 by inertial force to enter thedust collector 60 through therear end aperture 55 of thecircular wind passage 53. Part of the dust and debris flown in thedust collector 60 enters thenegative pressure room 70 via the net filter F3. On this occasion, the larger and heavier of the dust and debris is captured in thedust collector 60. - The air that has flown in the
negative pressure room 70 passes through apleat filter 100 to be absorbed in theelectric blower 33. After the air cools theelectric blower 33, it is discharged out of an exit (not shown) of thehousing 30 to the outside. On this occasion, the thin dust flown in thenegative pressure room 70 is captured by thepleat filter 100.
First, the operation when thehandle 100 is stood up is explained below.
With respect to the vacuum cleaner, when an operator holds thehandle 200 and lift thebody 20, thehandle 100 stands up from a storing position (position P ofFigure 16 ) ofFigures 7 and8 to a using position (position Q ofFigure 16 ) ofFigures 9 and10 . According to this, therack 316 that interlinks with thehandle 200 is pulled upward as shown inFigure 10 through thelink 318. - In accordance with this, the
pinion 315 can be rotated, whose rotation is transmitted to therack 303 through thegear 314, thepinion 313, and thepinion 313. Theslider 302 having therack 303 is moved (gone one way) in the direction of an arrow A1 from a left position (position P ofFigure 17 ) ofFigure 7 to a right position (position Q ofFigure 17 ) ofFigure 9 . - Under the situation, the
dust dumping member 304 of theslider 302 ofFigures 13 and14 is moved (gone one way) in the direction of an arrow A1 together with theslider 302. Thefirst engagement portion 305a provided on thedust dumping unit 305 of thedust dumping member 304 engages with, and climbs over, thefold 100a of the pleat filter, as shown inFigure 14 . Thefold 100a is repelled strongly by thefirst engagement unit 305a to vibrate thepleat filter 100. This movement is performed sequentially with respect to a lot offolds 100a, by which the thin dust attached to the upstream surface of thepleat filter 100 is dropped to be captured in thethin dust collector 74.
Next, the operation when thehandle 100 is laid down is discussed hereinbelow.
When thebody 20 is moved to a cleaning surface and the handle is released, thehandle 200 is lowered from a using position (position Q ofFigure 16 ) ofFigures 9 and10 to a storing position (position P ofFigure 16 ) ofFigures 7 ,8A and 8B by a force of thecoil spring 323. - According to this, the
pinion 315 is rotated, whose rotation is transferred to therack 303 through thegear 314, thepinion 313, and thepinion 312. Theslider 302 having therack 303 is moved (returned) in the direction of the arrow A2 from a right position (position Q ofFigure 17 ) ofFigure 9 to a left position (position P ofFigure 17 ) ofFigure 7 . - On this occasion, the
dust dumping member 304 of theslider 302 inFigures 13 and14 is moved (returned) together with theslider 302 in the direction of the arrow A2. When thesecond engagement portion 305b located on thedust dumping portion 305 of thedust dumping member 304 engages sequentially with, and climbs over, thefold 100a of thepleat filter 100, thedust dumping member 304 rotates in the direction of the arrow A3 around theinstallation boss 306 until theleg 308 hits the supportingwall 310. This allows thesecond engagement portion 305b to repel weakly than thefirst engagement portion 305a to vibrate the pleat filter100. This movement is performed sequentially with respect to a lot offolds 100a, so that the thin dust attached to the upstream surface of the pleat filter100 is dumped to be collected in thethin dust collector 74.
Winding operation of thepower cord 34b is explained hereinafter.
Based on this operation, because a lot offolds 100a of thepleat filter 100 is always repelled by at least one of the twodust dumping members handle 200 is lowered to the storing position (position P ofFigure 16 ) ofFigures 7 and8 by a force of thecoil spring 323 and is stored in thehandle storing unit 30a by the coil spring (handle storing spring) 323, the upper ends of the guide slits 319 and 319 come into contact with theguide protrusions - Under the situation, the
leg 200a of thehandle 200 contacts with the upper end of the brake release lever 325 (position P ofFigure 16 ), as shown inFigures 11 and 12 , by the weight of thehandle 200 itself. At the same time, because the supportingaxis 318b of thelink 318 is located in the upper end in the vertical direction of theoval hole 318a, the handle can be lowered further. - However, in this state, since the upper ends of the guide slits 319 and 319 are in contact with the
guide protrusions rack 316 cannot be lowered even if thehandle 200 is further pressed down. Therefore, theslider 302 does not move in the direction of the arrow A2 from the position Q ofFigure 17 to hit thefilter frame 100b of thepleat filter 100. - The
handle 200 is further pressed down to lower thebrake release lever 325 by theleg 200a of thehandle 200. When therubber roll 328 is lifted upward away from thebrake drum 34a, the brake of thecord reel 34 is released by therubber roll 328. As a result, thepower cord 34b is wound around thecord reel 34 by a force of a spiral spring (not shown). - Accordingly, even if the
handle 200 is further pressed down from the handle storing position, thebrake release lever 325 by theleg 200a of thehandle 200 is lowered, and the brake of thecord reel 34 is released by therubber roll 328, theslider 302 and thedust dumping member 304 are not moved. Consequently, it can be avoided beforehand that theslider 302 and thedust dumping member 304 are damaged by releasing the brake through a handle operation. - According to the embodiment, the dust dumping member can be driven with a simple structure.
In the embodiment, the dust of thepleat filter 100 is removed. However, a paper pack filter can be employed instead. The dust of the paper pack filter can removed by vibrating the paper pack filter, using a member that moves linking with the vertical motion of the handle.
The handle is provided to be isolated, so that the grip is designed to move vertically. However, the handle may be attached to the vacuum cleaner body so that it moves simply vertically. - Reciprocation motion by the dust dumping member enables the dust of the filter to be dumped effectively.
- Since the dust dumping member can go one way making use of a repelling force of gravity of the vacuum cleaner body when the handle is lifted, the first load produced between the dust dumping member and the filter can be made larger when the handle is lifted upward by a manual operation. Consequently, a larger vibrating force can be applied to the filter (100) from the dust dumping member (304).
When the handle is returned to the storage position by means of a spring force of the storage spring (coil spring 323), the second load produced between the dust dumping member and the filter is made smaller than the first load when the handle is moved downward to the storage position by the storage spring. Because only the spring force of the storage spring (coil spring 323) can return the dust dumping member, a vibration can be applied to the filter from the dust dumping member to remove the dust even if the storage spring (coil spring 323) has a weak spring force. - The C surface or R surface other than the inclined surface can be used as the second guide (
second engagement portion 305b). On this occasion, when the dust dumping member returns owing to a spring force of the storage spring (coil spring 323), it may rotate in the direction opposite to the movement direction (returning direction) or do not have to rotate. - While preferred embodiments of the invention have been described and illustrated above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as being limited by the foregoing description, and is only limited by the scope of the appended claims.
It is explicitly stated that all features disclosed in the description and/or the claims are intended to be disclosed separately and independently from each other for the purpose of original disclosure as well as for the purpose of restricting the claimed invention independent of the composition of the features in the embodiments and/or the claims.
