Description

  The present invention relates to a vacuum cleaner having a dust suction hose connected to a vacuum cleaner main body and an extension pipe connected to a grip pipe portion of the hose.

  A dust suction hose provided in a conventional electric vacuum cleaner can be attached to and detached from the vacuum cleaner main body, but this dust suction hose is usually held in a state of being connected to the vacuum cleaner main body. A suction port body is connected to the grip tube portion of the dust suction hose via an extension tube, and this connection is usually usually maintained. As described above, the dust suction hose, the extension pipe, and the suction port that are normally held in a mutually connected state constitute a dust suction system for the cleaner body.

  At the time of cleaning, the user grasps the grip pipe part of the dust suction system and moves the suction port body to an intended cleaning place through the extension pipe. In this cleaning, a suction port suitable for a cleaning place and a cleaning target is selected from various suction ports prepared in advance and used. In this case, the suction port is used by being connected to the tip of the extension tube or the grip tube of the dust suction hose. For this reason, the extension pipe is detachably fitted and connected to the grip pipe portion of the dust suction hose.

Then, when storing the vacuum cleaner, etc., the rear portion of the vacuum cleaner main body is placed in a standing position so as to be opposed to the floor surface in the room, and in this state the engagement concave portion of the vacuum cleaner main body opened upward A technique is known in which an attachment claw provided on an extension pipe is hooked from above and the extension pipe is held upright. With the extension pipe set up in this manner, the dust suction system has the suction port disposed below the extension pipe, the grip tube portion of the dust suction hose is disposed continuously above the extension pipe, and the dust suction system. The hose part of the hose is arranged so as to hang freely from the upper end of the grip pipe part over the main body suction port facing the upper side of the cleaner body in the standing position (see, for example, Patent Document 1).
JP 2002-28108 A (paragraphs 0012-0108, FIGS. 1 to 23, especially paragraphs 0016, 0037, 0038, 0042, 0050, 0053, 0054, 0057)

  The vacuum cleaner stored in a state where the dust suction system is assembled as in Patent Document 1, that is, the dust suction hose, the extension pipe, and the suction port body are connected to each other is held in a standing state. The grip tube portion of the dust suction hose is continuously arranged on the upper side of the extension tube. Therefore, this vacuum cleaner is unsuitable for storing in a low closet or a low shelf.

  In order to adapt to such storage, the grip tube portion of the dust suction hose may be removed from the extension tube. However, in this case, since the grip tube portion of the dust suction hose is not restrained, the grip tube portion is arbitrarily oriented in a free direction, which is inconvenient in that the accommodation for storing the dust suction hose is deteriorated. In addition, if the extension pipe with the dust suction hose removed is stored without being held by the vacuum cleaner body, when removing the vacuum cleaner main body with the dust suction hose connected, the grip pipe part will not fall and hit the floor. It is also inconvenient in that it takes time to take out from the storage location while taking into account the above.

  An object of the present invention is to provide a vacuum cleaner that can be stored in a storage place in a compact and well-contained manner and that has good workability for taking out from the storage place.

  In the present invention, the upstream end of the grip tube portion of the dust suction hose connected to the cleaner body and the downstream end of the extension tube connected to this end portion are rotatably connected by a connecting means. Then, the grip tube portion and the extension tube in a disconnected state are rotated so as to be bent around the connecting means, and the grip tube portion is arranged side by side with the extension tube. I am doing so.

  According to the vacuum cleaner of the present invention, since the grip tube portion can be arranged side by side with the extension tube, it can be stored in a compact manner, and furthermore, since both ends of the dust suction hose are constrained, the fit in the retracted state is reduced. In addition to this, it is possible to improve the workability of taking out from the storage location.

  A first embodiment of the present invention will be described with reference to FIGS.

  1 and 2, reference numeral 1 denotes a canister type vacuum cleaner. The vacuum cleaner main body 2 provided in the electric vacuum cleaner 1 can be easily moved on the surface to be cleaned by a caster (not shown) attached to the lower surface of the front part and a wheel 3 attached to the rear part. An electric blower (not shown) is built in the rear part of the cleaner body 2. A dust collector (not shown) is provided at the front of the cleaner body 2 on the upstream side of the electric blower, and a main body suction port (not shown) located on the upstream side of the dust collector is a vacuum cleaner body 2. It is provided open to the front of the.

  As shown in FIGS. 1 and 2, the vacuum cleaner main body 2 can be placed in a standing position by bringing the rear surface 2a and wheels 3 of the rear portion thereof into contact with a vacuum cleaner placing surface such as a floor surface of a room. In the state, a main body suction port (not shown) is directed upward. Further, a nail support 4 is provided on the lower surface of the cleaner body 2 facing the floor of the room when in use. The claw receiver 4 includes an engaging recess that opens upward when the cleaner body 2 is in the standing position.

  Reference numeral 11 in FIGS. 1 and 2 denotes a dust suction system. The dust suction system 11 includes a dust suction hose 12, an extension pipe 21, and a suction port body 31 that communicate with each other.

  The dust suction hose 12 is formed by connecting the grip tube portion 14 to the upstream end portion of the flexible hose portion 13 and connecting the connection tube 15 to the downstream end portion of the hose portion 13.

  The hose portion 13 has flexibility so that it can be freely deformed in a bellows shape. The connection pipe 15 is detachably connected to the main body suction port of the cleaner body 2. Normally, this connection is maintained, so that the dust suction hose 12 is carried along with the cleaner body 2.

  The grip tube portion 14 is gripped when the user has the dust suction system 11, and in the case of the present embodiment, as shown in FIGS. 3 and 4, the tube portion 16 and the grip portion 17 It has.

  The tubular body portion 16 having both ends opened in the axial direction is formed of a tube bent in a substantially square shape so as to bend downward in a state where the grip tube portion 14 is gripped, for example. It may be. A packing 18 formed in a ring shape with rubber is attached to the upstream end portion 16a of the tube body portion 16 forming the distal end portion of the grip tube portion 14 so as to cover the distal end surface thereof. The upstream end of the hose portion 13 is connected to the downstream end of the tube portion 16.

  The grip portion 17 is provided on the outer surface of the tube portion 16 so as to protrude obliquely rearward, and the grip portion 17 covers the tube portion 16, the hose portion 13 and the connecting portion from above. The grip part 17 is provided with an operation part 19 for giving a control command to the electric blower (not shown). The grip tube portion 14 may be configured such that the grip portion 17 is omitted and the tube portion 16 itself is gripped.

  The extension pipe 21 is, for example, a double joint provided with an upstream pipe 22 and a downstream pipe 23 slidably fitted in the axial direction, and can be expanded and contracted by the sliding. 1 and 2 show a state in which most of the upstream side pipe 22 is accommodated in the downstream side pipe 23 and is shortened. In this shortened state, the total length of the field extension pipe 21 is longer than the height of the cleaner body 2 in the standing state. A packing 24 formed in a ring shape with rubber covering the tip end surface thereof is bonded to an end portion 23a of the downstream side tube 23 which forms the downstream side end portion of the extension pipe 21. The packing 24 has the same shape as the packing 18 of the grip tube portion 14 and can be brought into contact with and separated from the packing 18.

  As shown in FIGS. 3 and 4, the end 23 a of the downstream pipe 23 that forms the downstream end of the extension pipe 21, and the end 16 a on the upstream side of the tube body 16 that forms the tip of the grip pipe 14 Are connected by a connecting means such as a hinge 25 so as to be rotatable. The hinge 25 is provided approximately 180 ° away from the grip portion 17 with respect to the circumferential direction of the tube body portion 16 and the downstream side tube 23. The extension tube 21 and the grip tube portion 14 can be turned around the hinge 25 so as to be bent, whereby the grip tube portion 14 is arranged next to the extension tube 21 as shown in FIGS. Can be arranged.

  The dust collection system 11 maintains a state in which the tube body portion 16 of the grip tube portion 14 and the downstream side tube 23 of the extension tube 21 are continuously connected in a straight line, and a coupling means that can manually release this holding state. I have. This coupling means comprises a clamp 26 and a clamp receiver 27, for example.

  The clamp 26 is attached to the outer surface of the upstream end portion 16 a of the tube body portion 16 that forms the distal end portion of the grip tube portion 14. This clamp 26 is manually operated. The clamp receiver 27 is attached to the outer surface of the end 23 a of the downstream pipe 23 that forms the downstream end of the extension pipe 21. In a state where the tube body portion 16 of the grip tube portion 14 and the downstream side tube 23 of the extension tube 21 are continuously connected in a straight line, the clamp 26 is engaged with and disengaged from the clamp receiver 27 by manual operation. The clamp 26 and the clamp receiver 27 are provided approximately 180 ° apart from the hinge 25 with respect to the circumferential direction of the tube portion 16 and the downstream tube 23. The clamp 26 is attached to the end 23 a of the downstream pipe 23 that forms the downstream end of the extension pipe 21, and the upstream end of the tube section 16 that forms the tip of the pipe section 14 by gripping the clamp receiver 27. You may attach to 16a.

  By manually hooking (engaging) the clamp 26 to the clamp receiver 27, the tube body portion 16 and the downstream side tube 23 are maintained in a straight and continuous connection state. They come into contact with each other and come into close contact with each other so that air tightness is achieved between the tube body portion 16, the downstream side tube 23, and the field. By manually removing (disengaging) the catch of the clamp 26 from the clamp receiver 27, the grip tube portion 14 and the extension tube 21 around the hinge 25 are allowed to rotate.

  As shown in FIGS. 1 and 2, a claw base 28 is fixed to the outer surface of the end side end portion of the upstream pipe 22 of the extension pipe 21, and a locking claw 29 is integrally projected on the claw base 28. Yes. The locking claw 29 can be engaged with and disengaged from the claw receiver 4.

  The suction port body 31 is detachably fitted to and attached to the end of the upstream pipe 22 of the extension pipe 21. The suction port body 31 shown in FIGS. 1 and 2 is mainly used for floor cleaning, and is normally held in a state where it is attached to the end of the upstream side pipe 22. However, when another suction port body prepared separately as an attachment, for example, a suction nozzle for a gap is used, it is replaced with the end of the upstream side tube 22.

  The end 23a of the downstream pipe 23 provided in the extension pipe 21 of the dust collection system 11 connected to the cleaner body 2 and the upstream end 16a of the pipe part 16 provided in the grip pipe part 14 are provided by the user. When the grip tube portion 14 of the electric vacuum cleaner 1 is gripped for cleaning, the connection state is maintained in a straight line. This holding is performed by the coupling means and the hinge 25 formed by engaging the clamp 26 with the clamp receiver 27. This state is shown in FIG. In this state, the packing 18 of the grip tube portion 14 and the packing 24 of the extension tube 21 come into contact with each other, and the airtightness between the grip tube portion 14 and the extension tube 21 is ensured. It is possible to prevent outside air from being sucked in between the extension pipe 21 and the extension pipe 21.

  There are two storage states of the electric vacuum cleaner 1 after cleaning, the first storage state is shown in FIG. 2, and the second storage state is shown in FIG.

  In the first retracted state, with the dust suction system 11 connected to the cleaner body 2, the locking claw 29 of the dust suction system 11 is engaged with the claw receiver 4 of the cleaner body 2 in the standing position. As a result, the extension pipe 21 of the dust collection system 11 is erected. At the same time, after removing the clamp 26 from the clamp receiver 27, the grip tube portion 14 is rotated downward so as to be bent around the hinge 25, and the grip tube portion 14 is supported on the cleaner body 2 in a standing manner. The extension pipes 21 are arranged side by side. As a result, the end portion 23a of the downstream tube 23 of the extension tube 21 and the upstream end portion 16a of the tube body portion 16 of the grip tube portion 14 are opened side by side. The above arrangement work with the rotation of the grip tube portion 14 may be performed before or after the extension tube 21 is supported on the cleaner body 2 in a standing manner.

  In the first retracted state, the grip tube portion 14 of the dust suction hose 12 is not continuously disposed on the upper side of the extension tube 21 held upright on the cleaner body 2. Therefore, the height space corresponding to the grip tube portion 14 of the dust suction hose 12 can be stored without considering it on the upper side of the extension tube 21. Therefore, it can be stored in a storage place where there is no sufficient upper space on the stored vacuum cleaner 1, such as a low closet or a low shelf.

  In the first retracted state, the grip tube portion 14 of the dust suction hose 12 and the extension tube 21 are maintained in a connected state by the hinge 25 although they are not in communication. In other words, the grip tube portion 14 of the dust suction hose 12 is restrained by the hinge 25 on the extension tube 21 that is supported upright on the cleaner body 2. The connection pipe 15 of the dust suction hose 12 is connected to the main body suction port of the cleaner body 2 and is restrained by the cleaner body 2. That is, both ends of the dust suction hose 12 are restrained in the first retracted state.

  Therefore, as in the case where the grip tube part 14 of the dust suction hose 12 is not restrained, the grip tube part 14 can be stored in such a manner that the grip tube part 14 faces freely in the direction of storing the dust suction hose 12 without deterioration. Therefore, when the vacuum cleaner 1 is used next time, when the vacuum cleaner 1 is taken out of the storage place, the dust suction system 11 can be taken out together with the cleaner main body 2 and the grip pipe portion 14 is held with one hand. Even if it is not, since the grip tube portion 14 does not fall and collide with the floor surface of the room, it is easy to use such as not being damaged due to the collision.

  Moreover, in the first retracted state, the grip tube portion 14 is rotated so that the end portion 16a of the grip tube portion 14 of the dust suction hose 12 is opened upward, so that the downstream end of the tube portion 16 is provided. As shown in FIG. 2, the upstream end 13a of the hose portion 13 of the dust suction hose 12 connected to the portion does not bend abruptly due to the weight of the hose portion 13 and is in a straight state. Thereby, the load with respect to the upstream side edge part of the hose part 13 can be reduced.

  In the second retracted state, the grip tube part 14 and the extension pipe 21 connected by the hinge 25 are connected to the cleaner body 2 with the dust suction system 11, and the end parts 16 a The engaging claw 29 of the dust suction system 11 is engaged with the claw receptacle 4 of the cleaner body 2 in the standing position while the end 23a is connected in a straight line. Thereby, after raising the extension pipe 21 of the dust collection system 11, the vacuum cleaner 1 is stored.

  In the second retracted state, the grip tube portion 14 of the dust suction hose 12 is continuously disposed on the upper side of the extension tube 21 held in the standing state. For this reason, since it is unsuitable for storing in a low closet or a shelf with a low height, it is selected when there is a sufficient upper space on the stored vacuum cleaner 1.

  In the second storage state, the connection pipe 15 of the dust suction hose 12 is connected to the main body suction port of the cleaner body 2, and the extension pipe 21 supported in a standing state on the cleaner body 2 has a dust absorption The grip tube portion 14 of the hose 12 is connected by a hinge 25 and a coupling means. That is, both ends of the dust suction hose 12 are restrained. Therefore, as in the case where the grip tube part 14 of the dust suction hose 12 is not restrained, the grip tube part 14 can be stored in such a manner that the grip tube part 14 faces freely in the direction of storing the dust suction hose 12 without deterioration. Therefore, when the vacuum cleaner 1 is used next time, when the vacuum cleaner 1 is taken out of the storage place, the dust suction system 11 can be taken out together with the cleaner main body 2 and the grip pipe portion 14 is held with one hand. Even if it is not, since the grip tube portion 14 does not fall and collide with the floor surface of the room, it is easy to use such as not being damaged due to the collision.

  A second embodiment of the present invention will be described with reference to FIGS. Since the second embodiment is basically the same as the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

  In the second embodiment, a communication pipe 35 is provided instead of providing an airtight holding packing at the upstream end of the grip pipe portion 14 and the downstream end of the extension pipe 21.

  The communication pipe 35 is formed in a bellows shape with a synthetic resin or the like, and does not include a spiral conductive metal coil like the hose portion 13, but can be expanded and contracted following an external force. It has been. The communication pipe 35 is provided across the upstream end portion 16 a of the tube body portion 16 of the grip tube portion 14 and the end portion 23 a of the downstream tube 23 of the extension tube 21. The body part 16 and the downstream pipe 23 of the extension pipe 21 are always in communication. For this purpose, one end of the communication pipe 35 is inserted inside the upstream end 16 a of the tube body part 16 and is fixed by an adhesive (not shown), and the other end of the communication pipe 35 is the end of the downstream pipe 23. It is inserted inside 23a and fixed with an adhesive (not shown).

  As shown in FIG. 5 and FIG. 7, the communication pipe 35 is supported by the grip pipe section 14 being erected on the cleaner body 2 by rotating the grip pipe section 14 downward so as to bend around the hinge 25. When arranged side by side with the extension tube 21, it can be bent in an inverted U shape. At the same time, as shown in FIG. 6, the communication pipe 35 has an axial length in a connection state in which the end 16 a of the grip pipe 14 and the end 23 a of the downstream pipe 23 of the extension pipe 21 are continuously connected. Is shortened so as to be covered with the grip tube portion 14 and the extension tube 21. Note that the connection state in which the end portion 16a of the grip tube portion 14 and the end portion 23a of the downstream side tube 23 of the extension tube 21 are continuously connected is held by the hinge 25 and the coupling means as described above.

  Except for the matters described above, the second embodiment is the same as the first embodiment. Therefore, also in the second embodiment, for the reason already described in the first embodiment, the vacuum cleaner can be compactly stored, can be stored well in the storage location, and can be easily taken out from the storage location. In addition, by providing the communication pipe 35 that allows the pipe body part 16 of the grip pipe part 14 and the downstream pipe 23 of the extension pipe 21 to communicate with each other, the outside air is introduced between the grip pipe part 14 and the extension pipe 21 during cleaning. It is excellent in that there is no fear of being inhaled.

  A third embodiment of the present invention will be described with reference to FIGS. Since the third embodiment is basically the same as the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof is omitted.

  In the third embodiment, instead of providing an airtight holding packing and a coupling means at the upstream end of the grip tube portion 14 and the downstream end of the extension tube, the tube portion 16 of the grip tube portion 14 is provided. A connecting means that allows the upstream end 16a and the end 23a of the downstream pipe 23 of the extension pipe to be detachably fitted is employed.

  The hinge 25 constituting this connecting means is formed by a first arm 41 and a second arm 51.

  The first arm 41 protrudes integrally from the distal end portion of the grip tube portion 14, that is, the outer surface of the upstream end portion 16 a of the tube body portion 16. The first arm 41 has a portion 41a extending in the axial direction of the grip tube portion 14, and this portion 41a faces the outer surface of the end portion 16a and forms a slight gap with the outer surface. .

  A first side projection 42 and a second side projection 43 are integrally provided on both side surfaces of the portion 41a. The first side projection 42 is provided on the distal end side of the portion 41a, and the second side projection 43 is provided on the root side of the portion 41a, whereby the first side projection 42 and the second side projection 43 are provided. Are spaced apart from each other in the axial direction of the tube portion 16.

  The second arm 51 protrudes integrally with the outer surface of the end 23a of the downstream pipe 23 that forms the downstream end of the extension pipe. The second arm 51 has a portion 51a extending in the axial direction of the downstream side pipe 23, and this portion 51a faces the outer surface of the end portion 23a and forms a slight gap with the outer surface. .

  The part 51a has a pair of sandwiching plate portions 52 that can be elastically deformed and overlap the side surface of the part 41a. A hinge small hole 53 and a hinge long hole 54 are respectively provided in the sandwiching plate portions 52. The hinge small hole 53 can be engaged with and disengaged from the first side projection 42 and the second side projection 43. The length of the hinge long hole 54 is shorter than the separation distance between the first side projection 42 and the second side projection 43. The hinge elongated hole 54 can also be engaged with and disengaged from the first side projection 42 and the second side projection 43.

  The hinge 25 configured as described above has at least the first side protrusion 42 fitted with the small hinge hole 53 or the long hinge hole 54 so that the tubular body portion 16 of the grip tube portion 14 and the downstream side tube 23 of the extension tube 21 are connected. It is connected.

  Specifically, as shown in FIG. 9A, in the state where the end 23a of the downstream pipe 23 of the extension pipe is fitted and connected to the upstream end 16a of the tube part 16 of the grip pipe part 14, A hinge small hole 53 is fitted to the first side projection 42 and a hinge long hole 54 is fitted to the second side projection 43 so that the grip tube portion 14 is connected to the extension pipe. In this state, a part of the upstream end portion 16a of the tube body portion 16 is inserted into the gap between the outer surface of the end portion 23a of the downstream tube 23 and the portion 51a of the second arm 51, and the downstream portion The end portion 23a of the side tube 23 and the end portion 16a on the upstream side of the tube body portion 16 are allowed to be fitted. In the state shown in FIG. 9A, the upstream end portion 16a of the tubular body portion 16 and the end portion 23a of the downstream side tube 23 are continuously connected in a straight line.

Thereby, the dust suction air passage at the time of cleaning is assembled. At the same time, the vacuum cleaner can be stored in the second storage state similar to that shown in FIG.

  A procedure for changing from the state shown in FIG. 9A to the first storage state similar to that shown in FIG. 2 will be described.

  First, as shown in FIG. 9B, the upstream end portion 16a of the tube body portion 16 and the end portion 23a of the downstream tube 23 are pulled away from each other to release these connections. As a result, the hinge small hole 53 is detached from the first side projection 42, while the hinge long hole 54 is detached from the second side projection 43 and fitted into the first side projection 42. In this case, the connection between the tubular body portion 16 and the downstream side pipe 23 is maintained by the fitting of the hinge elongated hole 54 and the first side projection 42. Note that the relative movement between the pipe body portion 16 and the downstream pipe 23 is allowed by the hinge elongated hole 54.

  Next, after the extension pipe is hooked on the cleaner body 2 in the standing state and supported in an upright state, as shown in FIG. 9C, the grip tube portion 14 and the extension pipe are used with the first side projection 42 as a fulcrum. As shown in FIG. 9D, the grip tube portion 14 is arranged so as to be aligned with the downstream tube 23 of the extension tube. In this case, not only the hinge long hole 54 is fitted to the first side projection 42, but also the small hinge 53 is fitted to the second side projection 43, so that the grip tube is connected to the extension pipe 21. The part 14 can be prevented from wobbling.

  With the above procedure, the vacuum cleaner can be brought into the first retracted state similar to that shown in FIG. Also, by carrying out the procedure opposite to the above procedure, the state shown in FIG. 9D is sequentially changed from the state shown in FIG. 9D to the state shown in FIG. The dust collection system can be assembled in a state suitable for the above.

  Except for the matters described above, the second embodiment is the same as the first embodiment. Therefore, also in the third embodiment, for the reason already described in the first embodiment, the vacuum cleaner can be compactly stored, can be stored well in the storage location, and can be easily taken out from the storage location. Moreover, in the third embodiment, by using the hinge 25 having the above-described configuration, the coupling means for maintaining the connection state between the tube body portion 16 of the grip tube portion 14 and the downstream tube 23 of the extension tube 21 is omitted. It is excellent in that it can be done.

  In the third embodiment, the first arm 41 is provided at the downstream end of the extension pipe 21 instead of being provided at the upstream end of the grip pipe part 14, and the second arm 51 is provided at the extension pipe. Instead of being provided at the downstream end portion of 21, it may be provided at the upstream end portion of the grip tube portion 14. Moreover, in 3rd Embodiment, it is also possible to add and carry out the bellows-shaped communication pipe 35 demonstrated in 2nd Embodiment.
