Description

  The present invention relates to a vertical vacuum cleaner, and more particularly to a vertical vacuum cleaner capable of performing floor cleaning using a suction port body and clearance cleaning using a clearance nozzle.

  Conventionally, as this type of vertical vacuum cleaner, a suction port body provided at the lower end of the vacuum cleaner body and having a suction port facing the floor surface, and a mounting tube formed integrally with the vacuum cleaner body An extension pipe having one end detachably connected to the mounting pipe, a hose connected to the other end of the extension pipe, and a dust collecting part connected to the hose and housed in the main body of the vacuum cleaner (For example, refer to Japanese Patent Laid-Open No. 10-43095; see Patent Document 1). The vacuum cleaner body accommodates a gap nozzle having an elongated opening at the tip. When cleaning the floor surface, the dust sucked from the suction port of the suction port body is collected in the dust collecting part via the attachment pipe, the extension pipe and the hose. On the other hand, when cleaning the corners and gaps of the floor surface, the operator removes one end of the extension pipe from the attachment pipe and removes the gap nozzle from the main body of the vacuum cleaner. The gap nozzle is attached to one end of the extension pipe, and the dust sucked from the tip of the gap nozzle is collected in the dust collecting section via the extension pipe and the hose.

However, when the conventional vertical vacuum cleaner moves from cleaning the floor surface to cleaning the gap, the operator removes one end of the extension pipe from the mounting pipe and removes the gap nozzle from the main body of the vacuum cleaner. It is necessary to remove and attach the gap nozzle to one end of the extension pipe. Therefore, there is a problem that it takes time and effort to move from floor cleaning to clearance cleaning.
Japanese Patent Laid-Open No. 10-43095

  Therefore, an object of the present invention is to provide a vertical vacuum cleaner that can quickly move from floor cleaning to clearance cleaning with little effort.

In order to solve the above problems, the vertical vacuum cleaner of the present invention is
A main body that houses the dust collector and the electric blower;
A suction port body connected to the lower part of the main body and having a suction port;
A main body vent pipe provided at the main body and having one end connected to the suction port;
One end part is detachably connected to the other end of the main body ventilation pipe, and an extension pipe in which a gap nozzle is provided so as to freely advance and retreat inside the one end part;
One end is connected to the other end of the extension pipe, and the other end is provided with a hose connected to the dust collecting portion of the main body.

  According to the above configuration, when one end portion of the extension pipe is connected to the other end of the main body ventilation pipe, the air sucked from the suction port of the suction inlet body by the operation of the electric blower is It is led to the dust collecting part via a path, the extension pipe, and the hose. On the other hand, when one end portion of the extension pipe is detached from the other end of the main body ventilation path, the gap nozzle is advanced to one end side of the extension pipe, and is sucked from the gap nozzle by the operation of the electric blower. The air is guided to the dust collecting part via the extension pipe and the hose. Thus, for example, the floor which sucks in dust on the surface of the floor from the suction port of the suction port body by a simple operation of separating the one end portion of the extension pipe from the other end of the main body ventilation path and moving the clearance nozzle forward. The surface cleaning can be shifted from the tip of the gap nozzle to the gap cleaning for sucking in dust such as floor corners and gaps. Therefore, one end of the extension pipe is removed from the attachment pipe, and the gap nozzle is removed from the main body of the vacuum cleaner, and the gap nozzle is integrated with the extension pipe. be able to.

  The gap nozzle has an opening narrower at one end than the opening at the other end, and effectively sucks in dust, for example, in the corners of the floor or in the gap between the furniture and the wall surface. This is what you can do.

  Further, the one end portion of the extension tube refers to a portion of the extension tube including one end and a portion near the one end.

In the vertical vacuum cleaner of one embodiment, the extension pipe has an extension pipe side through hole facing the other end of the main body ventilation pipe on a side surface in the vicinity of the one end.
The extension pipe side through hole is formed so as to be closed when the gap nozzle has advanced to one end side of the extension pipe, and opened when the gap nozzle has retreated to the other end side of the extension pipe. .

  According to the embodiment, when the extension pipe is connected to the main body ventilation pipe, the extension nozzle side through hole is opened by the clearance nozzle retreating to the other end side of the extension pipe. The extension pipe and the main body ventilation pipe communicate with each other through the opened extension pipe side through hole. Since the extension pipe and the main body ventilation pipe communicate with each other through the extension pipe side through hole, the air flowing from the main body ventilation pipe to the extension pipe can bypass a portion where the cross section of the extension pipe is relatively small. Therefore, the resistance to the air flowing from the main body ventilation pipe to the extension pipe can be effectively reduced. As a result, it is possible to effectively prevent a reduction in the suction work rate of the vertical vacuum cleaner.

In the vertical vacuum cleaner of one embodiment, the extension pipe has an extension pipe side through hole facing the other end of the main body ventilation pipe on a side surface of the one end portion.
The gap nozzle has a nozzle-side through hole on the side surface,
When the gap nozzle has advanced to one end of the extension pipe, the communication between the extension pipe side through hole and the nozzle side through hole is blocked, while the gap nozzle has retreated to the other end side of the extension pipe. At this time, the extension pipe side through hole and the nozzle side through hole are formed to communicate with each other.

  According to the embodiment, when the extension pipe is connected to the main body ventilation pipe, the gap nozzle is retracted to the other end side of the extension pipe, whereby the extension pipe side through hole and the nozzle side through hole are formed. Communicate. The extension pipe and the main body ventilation pipe communicate with each other through the extension pipe side through hole and the nozzle side through hole communicated with each other. Since the extension pipe and the main body ventilation pipe communicate with each other through the extension pipe side through hole and the nozzle side through hole, the air flowing from the main body ventilation pipe to the extension pipe has a relatively small cross section of the extension pipe. Can be bypassed. Therefore, the resistance to the air flowing from the main body ventilation pipe to the extension pipe can be effectively reduced. As a result, it is possible to effectively prevent a reduction in the suction work rate of the vertical vacuum cleaner. Further, as the gap nozzle advances and retreats, the extension pipe side through hole and the nozzle side through hole are communicated and blocked, so that the floor cleaning using the suction port body is surely performed with a simple structure, and the above Clearance cleaning using a clearance nozzle can be performed.

  In one embodiment, the vertical vacuum cleaner includes a closing member that closes an opening provided at a tip of a gap nozzle of the extension pipe when one end portion of the extension pipe is connected to the other end of the main body ventilation pipe. Prepare.

  According to the embodiment, when one end portion of the extension pipe is connected to the other end of the main body ventilation pipe, and the main body ventilation pipe and the extension pipe communicate with each other, the opening at the tip of the gap nozzle is closed. It is blocked by the member. Thereby, the air from the main body ventilation pipe is prevented from leaking from the gap nozzle. Therefore, it is possible to effectively prevent a reduction in the suction work rate when performing floor cleaning using the suction port body.

  In one embodiment, the extension pipe has a biasing member that biases the gap nozzle toward one end.

  According to the embodiment, when the extension pipe is separated from the main body ventilation pipe, the gap nozzle is biased by the biasing member, and the gap nozzle advances toward one end side of the extension pipe. Therefore, it is possible to effectively eliminate the trouble of removing the gap nozzle from the main body and attaching it to the tip of the extension pipe as in the past, and from the floor surface cleaning using the suction port body, easily and quickly using the gap nozzle. You can move on to cleaning.

  In the vertical vacuum cleaner according to an embodiment, the extension tube has an auxiliary brush formed at the one end portion so as to be movable forward and backward with respect to the extension tube and not separable.

  According to the said embodiment, when the said extension pipe is isolate | separated from the main body ventilation pipe, it can clean using this auxiliary brush by advancing the said auxiliary brush to the one end side of an extension pipe. Since the auxiliary brush is formed so as to be movable back and forth with respect to the extension tube and not separable, after the extension tube is separated from the main body ventilation tube, it can be easily and quickly cleaned with one touch.

  As described above, in the vertical vacuum cleaner of the present invention, one end portion of the extension pipe is detached from the other end of the main body ventilation path, and the gap nozzle provided inside the one end portion of the extension pipe is connected to the extension pipe. By advancing to one end side, it is possible to easily and quickly shift from floor cleaning using a suction port connected below the main body to clearance cleaning using the clearance nozzle.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 is a cross-sectional view showing a vertical vacuum cleaner according to an embodiment of the present invention. The vertical vacuum cleaner includes a vacuum cleaner body 1, a suction port body connecting portion 2 provided on a lower surface of the vacuum cleaner body 1 and connected to a suction port body (not shown), and the suction port body connecting portion. 2 is connected to one end of the main body ventilation pipe 3 formed in the vacuum cleaner main body 1, the extension pipe 4 connected to the other end of the main body ventilation pipe 3, and the extension pipe 4 and the handle 51. A hand pipe 5 having a hose 6 connected to the hand pipe 5, and a cyclone device 7 as a dust collecting portion connected to the hose 6 are provided.

  The distal end portion of the extension pipe 4 is detachably inserted into an extension pipe connecting portion provided on the upper surface of the electric vacuum cleaner main body 1. The other end of the main body ventilation pipe 3 is opened in the extension pipe connecting portion of the electric vacuum cleaner main body 1, and is formed so as to communicate the main body ventilation pipe 3 with the inserted extension pipe 4. ing. The extension pipe connecting portion has an engaging claw that engages with the distal end portion of the extension pipe 4. The engaging claw is formed so as to release the engagement with the extension pipe 4 by a release button provided on the upper surface of the electric vacuum cleaner main body 1. A gap nozzle 10 is housed inside the distal end portion of the extension pipe 4 so as to be able to advance and retreat, and an auxiliary suction port body 20 as an auxiliary brush is fitted to the outside so as to be able to advance and retreat.

  Further, the electric vacuum cleaner main body 1 includes an electric blower 30 that generates a suction air flow and a cord reel 31 that winds a power cord, which is connected to the downstream side of the cyclone device 7. In this vertical vacuum cleaner, most of the load is supported on a traveling wheel provided on a suction port body (not shown) connected to the suction port body connecting portion 2, and the handle 51 of the hand pipe 5 is provided to the operator. It is gripped and moved.

  The cyclone device 7 includes a cylindrical dust collecting case 71, and a cyclone main body 72 connected to the opening end of the dust collecting case 71. The cyclone main body 72 has an exhaust cylinder 73 protruding into the dust collection case, and a filter body 74 that filters air sucked from the exhaust cylinder 73. On the side surface of the dust collecting case 71 on the side of the main body of the vacuum cleaner, an opening 76 that guides sucked air is provided. The opening 76 communicates with the hose 6 through a passage in the electric vacuum cleaner main body 1.

  FIG. 2 is a cross-sectional view showing the distal end portion of the extension tube 4 and the gap nozzle 10 housed inside the distal end portion so as to freely advance and retract. FIG. 3 is a longitudinal sectional view showing the distal end portion of the extension tube 4 and the gap nozzle 10.

  As shown in FIGS. 2 and 3, the gap nozzle 10 is accommodated inside the distal end portion of the extension pipe 4, and the portion of the gap nozzle 10 accommodated in the extension pipe 4 is the extension pipe 4. It is formed so as to have an outer diameter slightly smaller than the inner diameter of the tip portion. A nozzle-side through-hole 11 is formed on the side surface of the gap nozzle 10 at the approximate center in the longitudinal direction. Further, the gap nozzle 10 has a lateral width that decreases from the vicinity of the edge on the tip side of the nozzle side through-hole 11 toward the tip, and an elongated rectangular opening 15 is formed at the tip in an end view. The edge of the opening 15 is inclined in an arc shape in a side view.

  An extension pipe side through hole 41 is formed on the side surface of the extension pipe 4 at a position slightly retracted from the tip.

  The nozzle side through hole 11 of the gap nozzle 10 and the extension pipe side through hole 41 of the extension pipe 4 are formed at the same circumferential position. When the gap nozzle 10 protrudes with respect to the extension pipe 4, the retreating side edge of the nozzle side through hole 11 comes into contact with the protruding side edge of the extension pipe side through hole 41. As a result, as shown in FIGS. 2 and 3, the gap nozzle 10 is locked to the extension pipe 4 and stopped at a predetermined protruding position, and the side surface of the gap nozzle 10 is extended to the extension pipe side through hole 41. The opening is closed. On the other hand, when the gap nozzle 10 is retracted with respect to the extension pipe 4, the gap nozzle 10 is locked to a locking portion (not shown) formed on the inner surface of the extension pipe 4, and the gap nozzle 10 is set to a predetermined level. It stops at the retreat position. In this retracted position, the nozzle side through hole 11 of the gap nozzle 10 and the extension pipe side through hole 41 of the extension pipe 4 overlap each other. Thereby, the inner side and the outer side of the extension pipe 4 communicate with each other through the nozzle side through hole 11 and the extension pipe side through hole 41.

  Further, although not shown in FIGS. 2 and 3, an auxiliary suction port body 20 as an auxiliary brush having a substantially cylindrical shape is slidably fitted in the longitudinal direction on the outer surface of the distal end portion of the extension pipe 4. ing. The auxiliary suction port 20 is planted with a brush extending in the longitudinal direction over substantially the entire circumference of the annular end surface. The auxiliary suction port 20 is inserted into the extension pipe connecting portion provided on the upper surface of the electric vacuum cleaner main body 1 together with the distal end portion of the extension pipe 4 and the gap nozzle 10. The auxiliary suction port body 20 is locked to the extension tube 4 at a protruding position where the tip of the brush protrudes from the tip of the extension tube 4 and a retracted position where the tip of the brush retracts from the tip of the extension tube 4. It is formed to do. When the auxiliary suction port body 20 in the protruding position is inserted into the extension pipe connecting portion of the electric vacuum cleaner main body 1, the release button of the auxiliary suction port body 20 is on the inner surface of the recess of the extension pipe connecting portion. By being pressed, the auxiliary suction port body 20 and the extension pipe 4 are disengaged from each other. Furthermore, a force directed to the other end side of the extension pipe 4 acts on the auxiliary suction port body 20 by friction between the outer side surface of the auxiliary suction port body 20 and the inner side surface of the extension pipe connecting portion. Yes. Thus, the auxiliary suction can be performed without the operator releasing and retreating the auxiliary suction port body 20 only by the operation of inserting the distal end portion of the extension tube 4 into the extension tube connecting portion. The mouth body 20 can be moved to the retracted position. When the tip of the extension tube 4 is pulled out from the vacuum cleaner main body 1, the release button provided on the upper surface of the vacuum cleaner main body 1 is operated, and the engagement claw of the vacuum cleaner main body 1 with respect to the extension tube 4 is operated. The engagement is released. And by the operation | movement which pulls out the said extension pipe | tube 4 from the vacuum cleaner main body 1, the said auxiliary | assistant suction opening body 20 with respect to an extension pipe | tube with the friction with the outer surface of the said auxiliary suction opening body 20 and the inner surface of an extension pipe | tube connection part Move relative to the protruding direction. Then, the auxiliary suction port body 20 reaches the protruding position, and the auxiliary suction port body 20 and the extension pipe 4 are engaged with each other. That is, only by the operation of pulling out the extension tube 4 from the main body 1 of the vacuum cleaner, the operator projects the auxiliary suction port body 20 without releasing the engagement and projecting the auxiliary suction port body 20. Can be moved to a position.

  The vertical vacuum cleaner having the above-described configuration operates as follows. First, as shown in FIG. 1, with the extension pipe 4 connected to the vacuum cleaner body 1, the suction port body is connected to the suction port body connecting portion 2 on the lower surface of the vacuum cleaner body 1. When the handle 51 is gripped by the operator and the power switch is turned on with the suction port of the suction port facing the floor surface, the electric blower 30 of the main body 1 of the vacuum cleaner is activated. As a result, the suction air flows through the suction port body, the main body ventilation path 3, the extension pipe 4, the hand pipe 5 and the hose 6, and the dust on the floor is sucked from the suction port of the suction port body. The sucked air is introduced into the dust collection case 71 together with dust from the opening 76 of the dust collection case, and a relatively large dust among the dusts is separated by the swirl flow generated in the dust collection case 71. The The suction air from which relatively large dust has been separated is guided to the filter body 74 through the exhaust cylinder 73 of the cyclone body, and fine dust is removed by the filter body 74 and is discharged from the electric vacuum cleaner body 1. The In this way, the floor surface is cleaned using the suction port.

  On the other hand, when cleaning a corner such as a corner of a floor surface or between a furniture and a wall, the auxiliary suction port body 20 and the gap nozzle 10 provided at the distal end portion of the extension pipe 4 are used.

  First, the operator operates the release button on the upper surface of the vacuum cleaner body 1 to release the lock between the extension pipe 4 and the extension pipe connecting portion. Subsequently, the operator applies an upward force to the handle 51 of the hand pipe, and the distal end portion of the extension pipe 4 is pulled out from the extension pipe connecting portion. At this time, the auxiliary suction port body 20 protrudes with respect to the extension pipe due to friction between the outer side surface of the auxiliary suction port body 20 fitted on the extension pipe 4 and the inner side surface of the extension pipe connecting portion. The auxiliary suction port 20 reaches the protruding position and engages with the extension pipe 4 by relative movement. Insert the tip of the extension pipe 5 where the auxiliary suction port 20 is in the projecting position into the gap between the furniture and the wall, etc., and let the brush 31 at the tip of the auxiliary suction port 20 face the floor of this gap. Clean the narrow space. At this time, since the auxiliary suction port body 20 covers and closes the extension pipe side through hole 41, the suction air does not leak through the through hole 41.

  When dust is sucked from a narrow gap or the like, gap cleaning is performed using the gap nozzle 10.

  First, the release button of the auxiliary suction port body 20 is pressed, the engagement of the auxiliary suction port body 20 with respect to the extension tube 4 is released, and the auxiliary suction port body 20 is retracted from the distal end of the extension tube 4 to the retracted position. Subsequently, the gap nozzle 10 that has been retracted with respect to the extension pipe 4 is pulled out to the protruding position. As a result, the side surface of the gap nozzle 10 closes the opening of the extension pipe side through hole 41. The tip of the gap nozzle 10 is inserted into a gap between the furniture and the wall, and dust on the floor surface of the gap is sucked from the opening 15 at the tip of the gap nozzle 10 to perform gap cleaning.

  When returning to floor cleaning after the clearance cleaning, the tip portion of the extension tube 4 is connected to the extension tube connecting portion of the electric vacuum cleaner main body 1. FIG. 4 is a schematic cross-sectional view showing the extension pipe connecting portion in a state where the extension pipe 4 is connected, and FIG. 5 is a vertical cross-sectional view showing the extension pipe connecting portion. FIG. 6 is a view of the extension pipe 4 and the gap nozzle 10 as viewed from the tip side. 4 and 5, the auxiliary suction port body 20 at the distal end portion of the extension pipe 4 is not shown.

  First, the distal end portion of the extension tube 4 is inserted into the extension tube connecting portion on the upper surface of the electric vacuum cleaner main body 1. At this time, the gap nozzle 10 protrudes from the distal end portion of the extension tube 4, while the auxiliary suction port body 20 recedes from the distal end of the extension tube 4. When the distal end portion of the extension tube 4 is inserted into the extension tube connecting portion in this state, first, the protruding tip portion of the gap nozzle 10 comes into contact with the sealing member 13 provided at the bottom of the extension tube connecting portion. . The sealing member 13 is provided with a recess in the opening-side surface of the extension pipe connecting portion, and is formed so that the tip portion of the gap nozzle 10 is accommodated in the recess. As the distal end portion of the extension tube 4 is inserted, the distal end portion receives a reaction force from the sealing member 13 and the gap nozzle 10 is immersed in the extension tube 4. As a result, the extension pipe side through hole 41 closed by the side surface of the extension pipe 4 is opened, and the end of the main body ventilation pipe 3 communicates with the opened extension pipe side through hole 41. Specifically, the extension tube side through hole 41 on the side surface of the extension tube 4 and the nozzle side through hole 11 on the side surface of the gap nozzle 10 overlap each other, and the overlapped extension tube side through hole 41 and nozzle side through hole 11 are overlapped. The main body ventilation pipe 3 and the extension pipe 4 communicate with each other. The packing 31 provided at the tip of the main body ventilation tube 3 is in close contact with the periphery of the extension tube side through hole 41 on the side surface of the extension tube 4, while the gap nozzle 10 provided at the tip portion of the extension tube 4. Since the sealing member 13 is in close contact with the tip of the air, the intake air from the main body ventilation pipe 3 flows into the extension pipe 4 without leakage.

  In addition, when the auxiliary suction port body 20 is inserted into the extension pipe connecting portion in a state of protruding from the tip of the extension tube 4, the release button is pressed on the inner side surface of the extension pipe connecting portion, The engagement between the auxiliary suction port body 20 and the extension pipe 4 is released. Thereafter, as the tip of the extension pipe 4 is inserted into the extension pipe connection part due to friction between the outer side surface of the auxiliary suction port body 20 and the inner side surface of the extension pipe connection part, the auxiliary suction port The body 20 moves to the retracted position. Thereby, the extension pipe side through hole 41 is exposed, the packing 31 of the main body ventilation pipe 3 is brought into close contact with the extension pipe side through hole 41, and the main body ventilation pipe 3 and the extension pipe 4 communicate with each other.

  In this way, the extension pipe 4 is connected to the extension pipe connecting portion, and dust on the floor surface is sucked from the suction port body below the vacuum cleaner main body 1, and this dust is discharged into the main body ventilation path 3, the extension pipe 4, It is collected in the cyclone device 7 via the hand pipe 5 and the inside of the hose 6.

  As described above, the distal end portion of the extension tube 4 can be attached to and detached from the extension tube connecting portion of the electric vacuum cleaner main body 1 in a state where the clearance nozzle 10 is accommodated in the inner end of the distal end portion of the extension tube 4 so as to be able to advance and retract. It is easier and quicker to move from floor cleaning to clearance cleaning and from clearance cleaning to floor cleaning. Further, since the extension pipe side through hole 41 is provided on the side surface of the extension pipe 4, it effectively prevents the gap nozzle 10 from becoming a resistance against the intake air flowing into the extension pipe 4 from the main body ventilation pipe 3. it can. Further, when the gap nozzle 10 moves backward with respect to the extension pipe 4, the extension pipe side through hole 41 and the nozzle side through hole 11 communicate with each other, while the gap nozzle 10 advances with respect to the extension pipe 4. Since the extension tube side through hole 41 is closed by the side surface of the gap nozzle 10, when the gap nozzle 10 is not used by connecting the main body ventilation pipe 3 and the extension pipe 4, the main body ventilation pipe 3 and the extension pipe 4 Can be communicated with a relatively small resistance, while the suction nozzle 10 can be reliably prevented from leaking when the gap nozzle 10 is used. Further, since the sealing member 13 for sealing the tip of the gap nozzle 10 is provided in the extension pipe connecting portion, it is possible to effectively prevent leakage of the suction air from the gap nozzle 10 when the main body ventilation pipe 3 and the extension pipe 4 are connected. Can be prevented.

  Further, since the auxiliary suction port body 20 as an auxiliary brush is provided at the tip of the extension pipe 4, when the extension pipe 4 is separated from the main body ventilation pipe 3, the auxiliary suction port body 20 is connected to the extension pipe 4. By advancing to the front end side, the gap cleaning using the auxiliary suction port body 20 can be performed easily and quickly with one touch.

  In the above embodiment, the gap nozzle 10 is driven back and forth in the extension pipe 4 by the operator, but a biasing member for biasing the gap nozzle 10 in the protruding direction may be provided in the extension pipe 4. Good. Thereby, when the said extension pipe | tube 4 is pulled out from the extension pipe | tube connection part, the clearance gap nozzle 10 can be protruded from the extension pipe | tube 4 without receiving operation by an operator. On the other hand, when the extension pipe 4 is inserted into the extension pipe connecting portion, the gap nozzle 10 comes into contact with the sealing member 13 so that the gap nozzle 10 can be immersed in the extension pipe 4 by the insertion operation of the extension pipe 4. it can.

  Further, the extension pipe 4 may not be provided with the auxiliary suction port body 20.

  In the above embodiment, the dust collection unit is a cyclone type that separates dust by generating a swirling flow of the suction air by the cyclone device 7, but is a paper pack type that collects dust in a disposable paper pack, for example. May be.
