  In an upright type vacuum cleaner equipped with an extended suction pipe, the extension suction pipe is troublesome. In addition, the upright type vacuum cleaner sometimes interrupts the cleaning using the extended suction pipe while cleaning the floor, but there is a problem that the extended suction pipe cannot be used immediately.

  An object of the present invention is to provide an upright type vacuum cleaner that addresses the above-described problems, that allows easy extension of the extension suction pipe, and that can be immediately cleaned using the extension suction pipe during floor cleaning. To do.

The present invention relates to a vacuum cleaner body having an electric blower and dust collecting means, a suction body provided at a lower portion of the vacuum cleaner body, a handle provided at an upper portion of the vacuum cleaner body, and a suction hose extending from the vacuum cleaner body. In an upright type vacuum cleaner provided at the tip and having an extended suction pipe that can be expanded and contracted, a storage cylinder portion that detachably houses the tip side of the extension suction pipe is provided in the cleaner body. Further, the storage cylinder is closed at the bottom, and the storage cylinder holds the tubular seal packing and the extended suction pipe stored in the storage cylinder so as not to come off at the receiving port of the storage cylinder. The extension suction pipe has a flange on the outer periphery of the extension suction pipe that can come into contact with the seal packing in a state where the extension suction pipe is stored in the storage cylinder portion. The portion is configured to be on the front side of the tub, and in a state where the extended suction pipe is stored in the storage cylinder portion, the front side of the ridge including the telescopic portion is inserted into the storage cylinder portion, and the suction pipe holding means is It has a lock pin that can be engaged with the bag when the extended suction pipe is housed in the housing cylinder, a lock urging spring, and a return lever that retreats the lock pin.

According to the present invention, the extension suction pipe is completed by inserting the distal end side of the extension suction pipe into the storage cylinder, and the extension suction pipe is removed from the storage cylinder so that the cleaning using the extension suction pipe is immediately performed. Can do. Further, according to the present invention, the air suction on the extended suction pipe side is maintained, the suction on the suction body side can be increased, and the extended suction pipe can be securely held in the storage cylinder portion.

  Hereinafter, examples according to embodiments of the invention will be described with reference to the drawings.

  First, a description will be given with reference to FIGS.

  The vacuum cleaner has a cleaner body 1, a suction body 2 that is detachably attached to a lower portion of the cleaner body 1, and a handle 3 that is foldable at an upper portion of the cleaner body 1.

  The handle 3 is rotatably supported on the handle support shaft 4 of the cleaner body 1, and normally the handle 3 is stood to clean the floor as shown in FIG. The handle 3 has a clamp 5. The clamp 5 restrains the handle 3 from being raised, so that the handle 3 is not folded during cleaning. At the time of storage, the handle 3 is folded as shown in FIGS.

  The suction body 2 is mainly used for cleaning the floor as shown in FIG. As shown in FIG. 5, the extension suction pipe 6 is used for cleaning the sofa, corners, and the like at a high place.

  The extension suction pipe 6 is provided at the distal end of a flexible suction hose 7 extending from the cleaner body 1 and is extendable. At a high place, the extended suction pipe 6 is extended for cleaning. In narrow places, the extended suction pipe 6 can be shortened. It can be used according to where you use it.

  As shown in FIGS. 4 and 5, the suction hose 7 is slidably supported by a hose guide ring 8 provided in the cleaner body 1. The extension suction pipe 6 is detachably inserted and attached to the storage cylinder portion 9 provided in the cleaner body 1. The vacuum cleaner main body 1 is provided with a C-shaped hose receiver 20 near the base of the handle 3.

  When cleaning using the extension suction pipe 6, the suction hose 7 is removed from the hose receiver 20, and the suction hose 7 slidable on the hose guide ring 8 is extended and cleaned. You can also clean high places.

  At the time of storage, the suction hose 7 contracted shortly is fitted and held in the hose receiver 20, and the extended suction pipe 6 is inserted into the storage cylinder portion 9. Thereby, since the suction hose 7 and the extension suction pipe 6 are settled so as to snuggle up to the cleaner main body 1 and do not sway, it is easy to finish.

  As shown in FIGS. 7 and 8, the suction body 2 includes a suction body portion 21 and a dust ventilation connection pipe portion 22 connected to the cleaner body 1.

  The suction body part 21 has a suction port 23, and the suction port 23 is provided with a rotating brush 24 that lifts up dust. The mouthpiece body 21 and the dust ventilation connecting pipe portion 22 are coupled via a pivotal coupling portion 25 that is pivotable. The mouthpiece body 21 and the dust vent connecting pipe portion 22 can be rotated so that the rotation coupling portion 25 is bent at a substantially right angle with the fulcrum as shown in FIG. 7 or straightly extended as shown in FIG.

  The suction port 23 of the suction body part 21 and the inside of the dust ventilation connection pipe part 22 communicate with each other through a passage of the rotation coupling part 25. The rotation coupling unit 25 also has a function as a suction port shutter. As shown in FIG. 7, the rotation coupling unit 25 is bent at a substantially right angle, whereby the suction port shutter is closed and the passage of the rotation coupling unit 25 is blocked. For this reason, the communication between the suction body 21 and the dust vent connection pipe portion 22 is closed.

  As shown in FIG. 8, the suction port shutter of the rotation coupling portion 25 is opened by rotating in a straight extending state, and the communication between the suction body portion 21 and the dust ventilation connection pipe portion 22 is maintained. Cleaning using the suction body 2 is performed in a state in which the suction body 2 extends substantially straight as shown in FIG.

  As shown in FIG. 7, when bent at a substantially right angle, the suction port shutter of the rotary coupling portion 25 is closed, so that cleaning using the suction body 2 is not possible. Instead, cleaning using the extended suction pipe 6 is performed. Although it is possible to perform cleaning using the extended suction pipe 6 even when the suction port shutter of the rotation coupling portion 25 is opened as shown in FIG. 8, the suction body 2 and the extended suction pipe 6 share the suction. This is undesirable because both suction forces are reduced.

  FIG. 12 is a view showing the dust flow path from the suction body 2 to the dust case 26 and the dust flow path from the extended suction pipe 6 to the dust case 26 in an easily understandable manner. As can be understood from this figure, the suction body 2 is communicated with the dust case 26 via the dust ventilation internal duct 27. The extended suction pipe 6 communicates with the dust case 26 from the middle of the dust ventilation internal duct 27.

  Thus, since the suction body 2 and the extended suction pipe 6 communicate with the dust case 26 so as to branch via the dust ventilation internal duct 27, when the shutter for the suction port of the rotational coupling portion 25 is opened. Closes the extension suction pipe 6 and performs cleaning by the suction body 2. When the shutter for the suction port of the rotation coupling part 25 is closed, the extension suction pipe 6 is used for cleaning.

  In this way, it is easy to clean the suction body 2 and the extended suction pipe 6 by bending the suction body 2 at a right angle (standing up the vacuum cleaner body 1) or straightening it (tilting the vacuum cleaner body 1). Is switched to. An easy-to-use vacuum cleaner can be provided.

  The rotation restraining means will be described with reference to FIG. 9, FIG. 10, and FIG.

  As described above, this electric vacuum cleaner is used with the vacuum cleaner body 1 set up or down. For this reason, the state which stood the vacuum cleaner main body 1 is hold | maintained reliably, and the rotation suppression means which can be easily rotated to the fall state is provided. This rotation suppression means is provided in the suction body 2.

  The mouthpiece portion 21 of the suction body 2 has an upper case 28 and a lower case 29 as shown in FIGS. 9, 10, and 11, the upper case 28 is removed and the inside of the lower case 29 is shown.

  The suction body portion 21 of the suction body 2 is provided with a large rear wheel 40 at an interval on the rear side of the suction opening 23. A small front wheel 41 is provided at the lower front side of the suction port 23. The axis of the rotation coupling part 25 is provided so as to be positioned in the vicinity of the rotation axis of the rear wheel 40. Since the suction body 2 is supported by four front and rear wheels, the suction body 2 can stand on its own with the vacuum cleaner body 1 standing.

  A leaf spring 42 is provided in the lower case 29 of the mouthpiece body 21 adjacent to the rotation coupling portion 25. The leaf spring 42 has a raised portion 43 extending vertically in the center. A protrusion 45 is provided on the rotation shaft 44 of the dust ventilation connecting pipe portion 22 constituting the rotation coupling portion 25. The protrusion 45 and the raised portion 43 of the leaf spring 42 form a rotation suppressing means.

  The rotation restraining means is provided so that the protrusion 45 and the raised portion 43 face each other, and the protrusion 45 is slid on the leaf spring 42. By rotating the dust ventilation connection pipe part 22 with respect to the suction body part 21, the protrusion 45 of the dust ventilation connection pipe part 22 abuts against the raised part 43 of the leaf spring 42. Further, when the dust ventilation connecting pipe portion 22 is turned strongly, the leaf spring 42 is bent and the raised portion 43 escapes and retreats, so that the protrusion 45 rotates beyond the top portion of the raised portion 43. When the protrusion 45 exceeds the top of the raised portion 43, the bending of the leaf spring 42 returns, so that the reverse rotation of the dust ventilation connecting pipe portion 22 is suppressed.

  The protrusion 45 and the raised portion 43 of the rotation suppressing means are positioned so that the rotation suppression in the reverse direction occurs when the cleaner body 1 is raised. For this reason, the cleaner body 1 is held in a standing state. That is, it is possible to prevent the cleaner body 1 from rotating so as to fall backward when the cleaner body 1 is positioned above the suction body 2. Since the vacuum cleaner main body 1 does not fall, cleaning at a high place using the extension suction pipe 6 can be performed without any trouble. When the vacuum cleaner main body 1 is tilted, it is rotated against the rotation restraining means by slightly turning it in the opposite direction.

  The structure of the cleaner body 1 will be described with reference to FIGS. 3, 1, 2, 22, 23, and 24.

  The main body case that forms the outline of the vacuum cleaner main body 1 includes a lower main body case 46 and an upper main body case 47. The handle 3 is rotatably attached to the upper part of the lower body case 46 using the handle support shaft 4.

  The electric blower 48, the cord reel 49, the dust ventilation inner duct 27, and the electric blower suction case 60 are accommodated in the main body case 46. The dust ventilation inner duct 27 is placed in the main body case 46 so that the cord reel 49 and the suction case 60 for the electric blower overlap on the lower side and the cord reel 49.

  As shown in FIGS. 22, 23, and 24, the dust ventilation internal duct 27 includes a joint holder 61, a communication pipe 62, and a dust case connection pipe 63. The joint holder 61 has a branch port 65 that communicates with the suction hose 64.

  The communication pipe 62 is provided with a flat portion 66 where the surface facing the cord reel 49 is crushed in a place overlapping the cord reel 49. Since the flat portion 66 is about half as thick as the other portions, the thickness of the main body case can be made thin and compact.

  However, in order to secure the air passage cross-sectional area at the flat portion 66, the width is increased in the lateral direction.

  The flat portion 66 is provided with a plurality of reinforcing ribs 67. When the blow pipe (synthetic resin) communication pipe 62 is heated, the flat portion 66 is likely to be thermally deformed. The reinforcing rib 67 can suppress thermal deformation of the flat portion 66.

  The intake valve for protecting the electric blower will be described with reference to FIG. 3 and FIG. 28, FIG. 29, and FIG.

  The electric blower protection intake valve 68 is attached to the connection ring 69 of the electric blower suction case 60. The connection ring 69 is connected to the suction portion of the electric blower 48 via the intervening ring 80.

  The electric blower protection intake valve 68 takes in outside air and suppresses the temperature rise of the electric blower 48. When the above-described suction port shutter of the rotation coupling portion 25 of the suction body 2 is closed and the suction of the extension suction pipe 6 is closed, the outside air flows in from the intake valve 68 for protecting the electric blower and is electrically driven. The temperature rise of the blower 48 can be suppressed.

  The electric blower protection intake valve 68 is located on the downstream side of the dust case 26 and on the suction side of the electric blower 48. The lower body case 46 is provided with a vent hole 81 through which outside air flows. This vent hole 81 is also provided between the downstream side of the dust case 26 and the suction side of the electric blower 48. Outside air is sucked into the electric blower 48 through the electric blower protection intake valve 68 provided so as to be located at the vent 81, and the temperature rise of the electric blower 48 is suppressed.

  The electric blower protection intake valve 68 includes a valve body 82 and a valve body biasing spring 83. The valve body urging spring 83 urges the valve body 82 to be closed. When the suction of the suction body 2 and the extended suction pipe 6 is closed and the negative pressure on the suction side of the electric blower 48 increases, the valve body 82 opens against the valve body biasing spring 83 and the outside air flows in. is there.

  As shown in FIGS. 3, 19, 20, and 21, the dust case 26, which is a dust collecting means, includes a cyclone dust collecting portion 84 that collects coarse dust, a fine dust collecting portion 85 that collects fine dust, and a cyclone dust collecting portion. 84 and a fine dust collecting portion 85 are detachably coupled to each other with an operation button 86 for coupling means.

  The cyclone dust collecting portion 84 has a dust inlet 87 that is detachably connected to the dust case connecting pipe portion 63. Further, the fine dust collecting unit 85 has a fine dust filter 88 and a dust removing device 89. The operation button 86 of the coupling means, the dust inlet 87, the fine dust filter 88, and the dust removing device 89 are provided on the back side of the dust case 26.

  The dust case 26 is detachably stored in a dust case storage unit 100 provided in the main body case 47 of the cleaner body 1. Since the dust case 26 is stored with the back side facing the inside of the dust case storage unit 100, the operation button 86, the dust inlet 87, the fine filter 88, and the dust removing device 89 are not visible from the front side, and the appearance is clean. Can provide a vacuum cleaner.

  The attachment / detachment of the dust case will be described with reference to FIGS.

  13 to 15 show the floor in which the dust case 26 is housed in the dust case storage unit 100. FIG. 16 to 18 show that the dust case 26 starts to be removed from the dust case storage unit 100.

  As shown in FIGS. 15 and 18, the upper portion of the dust case 26 is wider on the rear side (back side) than on the front side that is the front side. In addition, the front side of the dust case storage unit 100 is narrower than the back side. Moreover, the width of the rear side (back side) of the upper portion of the dust case 26 is slightly narrower than the width of the upper opening of the dust case storage unit 100.

  When the hook button 101 on the upper side of the dust case 26 is pressed to disengage the cleaner body 1 and the upper part of the dust case is slightly tilted so that the upper part of the dust case 26 is pulled out to the front side, the rear side (back side) of the dust case 26 becomes the dust case. It is held in contact between the openings of the storage unit 100.

  This holding prevents falling when the dust case 26 is removed. The dust case 26 is easy to remove.

  As shown in FIGS. 4, 5, and 6, a ridge protrusion 102 is provided on the lower side of the lower surface of the main body case 46, and a flock 103 is applied to the distal end side of the ridge protrusion 102. As shown in FIG. 6, when the floor surface is cleaned, the flocking 103 contacts the floor surface, so that the floor surface is not damaged.

  In addition, flocking 104 was also applied to the storage cylinder portion 9 on the lower side in contact with the floor surface. As shown in FIG. 6, when the floor surface is cleaned, the flocked hair 104 contacts the floor surface, so that the floor surface is not damaged.

  The work volume measurement of the vacuum cleaner will be described with reference to FIGS. 25, 26, and 27. FIG.

  The inner diameter of the joint holder 61 is formed so as to increase toward the outer side including the place where the branch port 65 is provided. Since the branch port 65 is closed by inserting the work measuring tube 105, a separate tool for closing the branch port 65 is unnecessary, and measurement can be performed easily.

  The extended suction pipe will be described in detail with reference to FIGS.

  The extension suction pipe 6 is formed by slidably combining a plurality of suction pipes 120, 121, and 122 having different thicknesses as shown in FIGS. A switching suction port 123 that can be switched by rotation is provided at the tip of the thin suction pipe 120.

  The extension suction pipe 6 is telescopic. Extend it long and clean high places such as the ceiling. Shorten and clean in a narrow area.

  The extension suction pipe 6 is provided with suction pipe locking means 124 and 125.

  The suction pipe locking means 125 is provided on the front side of the thick suction pipe 122. The suction pipe locking means 125 has an engaging protrusion 126. The engagement protrusion 126 is engaged with the engagement hole of the medium-sized suction pipe 121 and maintained in an extended state.

  When the knob 127 of the suction pipe locking means 125 is moved in the W direction, the engagement protrusion 126 is detached from the engagement hole and the restriction of the suction pipe locking means 125 is released. The middle suction pipe 121 can be shrunk so as to be accommodated in the thick suction pipe 122.

  The suction pipe locking means 124 is provided on the front side of the middle-sized suction pipe 121. The suction pipe locking means 124 has a lever 128, and the inner end projection of the lever 128 is engaged with the engagement hole 129 of the thin suction pipe 120 and maintained in an extended state.

  When the middle-thick suction pipe 121 is housed in the thick suction pipe 122, the lever 128 hits the suction pipe locking means 125, and the lever 128 operates in the outer circumferential direction. By this operation, the inner end protrusion of the lever 128 is released from the engagement hole 129 of the thin suction pipe 120, so that the restriction of the suction pipe locking means 124 is released. The thin suction pipe 120 can be shrunk so as to be accommodated in the middle-thick suction pipe 121.

  Thus, the extended suction pipe 6 is reliably held in the extended state by the restraint of the suction pipe locking means. The extended suction pipe 6 can be easily contracted by releasing the restriction of the suction pipe locking means.

  The switching inlet 123 is rotatably supported by the support shaft 140 at the tip of the thin suction pipe 120. The switching inlet 123 has two inlet parts 141 and 142. The suction port 141 is provided with a brush 143.

  By turning the switching suction port 123, the suction port 142 (FIG. 42) without the brush and the suction port 142 with the brush (FIG. 43) are switched.

  When the suction port 142 without a brush is set, the state is held by the detent holding means 144 (unevenness) as shown in FIG.

  When set in the mouthpiece 142 with the brush, as shown in FIGS. 40 and 41, the state is held by the detent holding means 145 (protrusion).

  Thus, switching of the switching suction port is easy because it is performed by turning. In addition, since both of the switched states are held by the non-rotating holding means, the switching suction port is not easily rotated during use and is easy to use.

As shown in FIGS. 31 and 32, the bottom portion of the storage cylinder portion 9 in which the extended suction pipe 6 is stored is closed. The storage tube portion 9 has a ring-shaped seal packing 146 at the receiving port. Extended suction pipe 6
The thick suction pipe 122 is provided with a flange 147 on its outer periphery.

  When the shortened extension suction pipe 6 is inserted into the storage cylinder portion 9, the flange 147 is brought into close contact with the seal packing 146 and airtightness is maintained. Since the bottom part of the storage cylinder part 9 is closed, the suction of the extension suction pipe 6 is cut off. Since only suction of the suction body 2 is performed, suction of the suction body 2 is performed well.

  In this way, since the shut-off valve or the like is not provided to close the suction of the extension suction pipe 6, the configuration is simple and inexpensive. Further, since the extension suction pipe 6 can be stopped from being sucked into the storage cylinder portion 9, the operation is simple.

  The storage cylinder portion 9 has a suction pipe holding means 148. The suction pipe holding means 148 is provided at the receiving port of the storage cylinder portion 9. The suction pipe holding means 148 includes a lock pin 149, a lock biasing spring 150, and a return lever 151.

  When the extension suction pipe 6 is inserted into the storage cylinder portion 9, the hook 147 is engaged with the lock pin 149 and is securely held in the storage cylinder portion 9. For this reason, during the floor cleaning by the suction body 2, the extended suction pipe 6 does not come off from the storage cylinder portion 9 and does not interfere with cleaning.

  The extension suction pipe 6 can be easily detached from the storage cylinder portion 9 by turning the return lever 151 so that the lock pin 149 moves backward.
