The machine body 3 is stored in a standing posture.

  When the suction port body 6, the extension pipe 5 and the cleaner body 3 which are integrally connected are mounted, the storage base 31 functions the fixing portion 17 to release the fixing between the inner pipe 15 and the outer pipe 16, A fixing release portion 32 that enables the extension tube 5 to be reduced is provided.

  FIG. 3 is a side view showing the stick type vacuum cleaner according to the first embodiment of the present invention.

  As shown in FIG. 3, the stick-type vacuum cleaner 1 according to the present embodiment has a standing posture by combining the suction port body 6, the extension pipe 5 and the vacuum cleaner body 3 that are integrally connected to the storage base 31. Thus, the projected area A (or installation area A) on the floor surface can be kept as small as possible. In FIG. 3, a state in which the extension tube 5 is most expanded is indicated by a two-dot chain line, and a state in which the extension tube 5 is most contracted is indicated by a solid line. At this time, the cleaner body 3 is connected to the upper end of the extension pipe 5, and the handle 2 is arranged near the top of the stick-type vacuum cleaner 1 in the standing posture.

  The storage base 31 includes a stopper 33 for placing the suction port body 6 at a fixed position. The stopper 33 prevents movement of the suction port body 6 so that the suction port body 6, the extension pipe 5, and the cleaner body 3 combined with the storage table 31 do not fall off the storage table 31. The stopper 33 also serves to support a reaction force when the push button 18 of the extension pipe 5 is pressed against the fixing release portion 32.

  Further, the storage table 31 includes a charging path 35 that is provided on the storage table 31 and supplies power to the secondary battery 11 when the cleaner body 3 is stored in the storage table 31. The charging path 35 includes a terminal 36 that is electrically connected to the secondary battery 11 when the cleaner body 3 is stored in the storage base 31. The vacuum cleaner body 3 is also provided with a terminal (not shown) that contacts the terminal 36 and electrically connects the charging path 35 and the secondary battery 11 when the vacuum cleaner body 3 is stored in the storage base 31.

  The fixing part 17 of the extension pipe 5 fixes the inner pipe 15 and the outer pipe 16 by the fixing release part 32 of the storage base 31 when the suction port body 6, the extension pipe 5 and the cleaner body 3 are attached to the storage base 31. To release. Specifically, the fixing release portion 32 of the storage base 31 is provided at a position where the push button 18 of the fixing portion 17 is pressed when the suction port body 6, the extension pipe 5 and the cleaner body 3 are combined with the storage base 31. It is a protrusion. The fixing release part 32 continues to push the push button 18 of the fixing part 17 as long as the suction port body 6, the extension pipe 5 and the cleaner body 3 are mounted on the storage base 31. That is, the extension pipe 5 is kept in a state where the inner pipe 15 and the outer pipe 16 are released from being fixed as long as the suction port body 6, the extension pipe 5, and the cleaner body 3 are mounted on the storage base 31. . Accordingly, the extension pipe 5 easily expands and contracts by lifting or lowering the cleaner body 3. Further, when the extension tube 5 can be reduced by the fixing release portion 32, the extension tube 5 is reduced by the weight of the cleaner body 3.

  Further, the extension pipe 5 extends in a series of operations to be removed from the storage base 31. Specifically, when the suction port body 6, the extension pipe 5, and the cleaner body 3 are removed from the storage table 31, the user first holds the handle 2 of the cleaner body 3 on the storage table 31. Then, the extension pipe 5 is pulled up in the expansion / contraction direction, and when the extension pipe 5 has been fully extended, the suction port body 6, the extension pipe 5 and the cleaner body 3 are integrally removed from the storage base 31, thereby extending the extension pipe 5. You can start cleaning.

  By the way, the inner tube 15 of the extension tube 5 has a remaining portion 25 having a predetermined length D that remains outside the outer tube 16 even when the extension tube 5 is most contracted.

  The user of the stick type vacuum cleaner 1 holds the handle 2 of the vacuum cleaner main body 3 with one hand and the other end of the outer tube 16 with the other hand, that is, the end near the vacuum cleaner main body 3. The extension tube 5 can be reduced by grasping 16a, releasing the fixation between the outer tube 16 and the inner tube 15 by the fixing portion 17, and bringing both hands closer to each other.

  The user of the stick type vacuum cleaner 1 holds the handle 2 of the vacuum cleaner main body 3 with one hand and the other end of the outer tube 16 with the other hand, that is, the side closer to the vacuum cleaner main body 3. The extension tube 5 can be extended by grasping the end portion 16a, releasing the fixation between the outer tube 16 and the inner tube 15 by the fixing portion 17, and keeping both hands away.

  When the extension tube 5 can be reduced to a state in which the outer tube 16 is substantially in contact with the cleaner body 3 in the expansion / contraction operation of the extension tube 5, particularly in the reduction operation, that is, the extension tube 5 is most shortened. If the inner tube 15 is concealed without being exposed, a part of the finger that holds the end 16a of the outer tube 16, for example, a ring finger from the little finger is placed between the outer tube 16 and the cleaner body 3, or the outer tube. 16 and the joint portion of the inner tube 15 may cause an unexpected injury to the user.

  Therefore, the inner tube 15 of the stick-type vacuum cleaner 1 according to the present embodiment has a remaining portion 25 having a predetermined length D that remains outside the outer tube 16 even when the extension tube 5 is contracted most.

  The remaining portion 25 may be at least 3 centimeters, for example, so as not to sandwich a part of a finger between the outer tube 16 and the cleaner body 3 or between the outer tube 16 and the joint portion of the inner tube 15.

  By the way, the conventional canister type vacuum cleaner is provided with the outer tube | pipe arrange | positioned at the hand side with a handle, and the inner tube | pipe arrange | positioned far from an outer tube | pipe seeing from a handle. The user holds the outer tube close to the handle with one hand, releases the fixation between the outer tube and the inner tube with the fixing part, and holds and extends an appropriate portion of the inner tube far from the handle with the other hand. The tube is stretched.

  On the other hand, the stick type vacuum cleaner 1 according to the present embodiment has a handle 2 in the vacuum cleaner body 3 that is heavier than the extension pipe 5 and the suction port body 6. In this stick type vacuum cleaner 1, a user who is accustomed to using a conventional canister type vacuum cleaner customarily holds the inner tube 15 close to the handle 2 with one hand, and is distant from the handle 2 with the other hand. There is a possibility that the fixing portion 17 may release the fixation between the outer tube 16 and the inner tube 15 while gripping the tube 16 and try to expand and contract the extension tube 5.

  And since the stick type vacuum cleaner 1 has the heavy vacuum cleaner main body 3 on the inner tube 15 side, the inner tube 15 close to the handle 2 is routinely gripped with one hand, and the other hand When the outer tube 16 far from the handle 2 is gripped and the fixing portion 17 releases the fixation between the outer tube 16 and the inner tube 15 and the extension tube 5 is to be expanded and contracted, the hand holding the inner tube 15 There is a possibility that the extension pipe 5 may be rapidly reduced in such a state that the gripping force cannot support the weight of the cleaner body 3 and falls due to its own weight. When the extension pipe 5 is suddenly reduced in a state where the vacuum cleaner body 3 falls due to its own weight, the user can place the space between the outer pipe 16 and the cleaner body 3 or between the outer pipe 16 and the inner pipe 15. There is a risk of fingers being pinched between the joint and injury.

  Therefore, the inner tube 15 of the stick-type vacuum cleaner 1 according to the present embodiment has a remaining portion 25 having a predetermined length D that remains outside the outer tube 16 even when the extension tube 5 is contracted most.

  The remaining portion 25 only needs to be at least 11 centimeters, for example, so that the entire finger is not sandwiched between the outer tube 16 and the cleaner body 3.

  That is, when gripping the handle 2 of the cleaner body 3 with one hand and gripping the end 16a of the outer tube 16 near the cleaner body 3 with the other hand, The remaining portion 25 only needs to be 3 centimeters or more, for example, so that a part of a finger is not sandwiched between the outer tube 16 and the cleaner body 3, and on the other hand, the inner tube 15 is gripped by one hand, When the outer tube 16 is gripped by hand and the extension tube 5 is expanded and contracted, the remaining portion 25 should not be sandwiched between the outer tube 16 and the cleaner body 3, for example, 11 cm or more. Therefore, the safety of the extension pipe 5 can be improved by securing the remaining portion 25 of 11 centimeters or more. The remaining portion 25 does not include the joint portion of the inner tube 15 and has the same outer diameter as that of the portion that protrudes into and out of the outer tube 16.

  In addition, the remaining portion 25 can be accommodated by the user or other than the user when the suction port body 6, the extension pipe 5 and the cleaner body 3 which are integrally connected are combined with the storage base 31 and stored in a standing posture. Others in the vicinity of the base 31 are prevented from being injured by being sandwiched between the contracting extension pipes 5, thereby improving the productivity.

  The stick type vacuum cleaner 1 according to the present embodiment configured as described above is provided with the extendable extension pipe 5, the vacuum cleaner main body 3, the extension pipe 5 and the suction port body 6 which are integrally connected. The extension pipe 5 can be reduced in size, and includes a suction port body 6, a reduced extension pipe 5 and a storage base 31 for storing the vacuum cleaner main body 3 in an upright position.

It is possible to shift to the storage state by a series of operations for mounting.

  Furthermore, the stick type vacuum cleaner 1 according to the present embodiment fixes the extension pipe 5 in a state in which the cleaner body 3, the extension pipe 5 and the suction port body 6 integrally connected to the storage base 31 are stored. Since the part 17 is released, the cleaning body 3, the extension pipe 5 and the suction port body 6 which are connected together are removed from the storage base 31 and then the cleaning starts smoothly with the extension pipe 5 extended. It is done.

  Moreover, the stick type vacuum cleaner 1 according to the present embodiment includes the storage base 31 that also serves as a charging stand, so that the integrally connected vacuum cleaner body 3, the extension pipe 5, and the suction port body 6 are in a cordless state. In addition, the secondary battery 11 can be charged when stored.

  Furthermore, since the stick type vacuum cleaner 1 according to this embodiment includes the extendable tube 5 that can be expanded and contracted, it can handle various usage scenes with improved handling performance even in a narrow place or a place close to the hand.

  Furthermore, the stick type vacuum cleaner 1 according to this embodiment includes an inner tube 15 disposed near the handle 2 of the cleaner body 3 and an outer tube 16 disposed farther than the inner tube 15. Accordingly, the extension tube 5 can be easily expanded and contracted by an operation of holding the handle 2 of the cleaner body 3 with one hand and holding the outer tube 16 with the other hand to bring both arms closer.

It is a protrusion.

  By the way, the extension pipe 5 of the stick type vacuum cleaner 1 does not change the distance from the suction port body 6 to the fixing part 17 even if the extension pipe 5 expands and contracts. Even if it is fixed to, the state where the fixing portion 17 is released can be maintained. On the other hand, the extension pipe 5A of the stick type vacuum cleaner 1A changes the distance from the suction port body 6 to the fixed portion 17A when the extension pipe 5A expands and contracts. Therefore, the fixing release portion 32A of the storage base 31A follows the expansion and contraction of the extension pipe 5A, that is, follows the movement of the fixing portion 17A.

  With this follow-up function, the fixing release portion 32A continues to push the push button 18A of the fixing portion 17A as long as the suction port body 6, the extension pipe 5A, and the cleaner body 3 are mounted on the storage base 31A. That is, the extension pipe 5A is maintained in a state where the inner pipe 15A and the outer pipe 16A are released from being fixed as long as the suction port body 6, the extension pipe 5A, and the cleaner body 3 are mounted on the storage base 31A. . Accordingly, the extension pipe 5A easily expands and contracts by lifting or lowering the cleaner body 3. Further, the extension pipe 5A is reduced by the weight of the cleaner body 3 when it can be reduced by the fixing release portion 32A.

  Further, the extension pipe 5A is continuously extended in the operation of being removed from the storage base 31A. Specifically, when the suction port body 6, the extension pipe 5 </ b> A, and the cleaner body 3 are removed from the storage base 31 </ b> A, the user first holds the handle 2 of the cleaner body 3 on the storage base 31 </ b> A. Then, the extension pipe 5A is pulled up in the expansion / contraction direction, and when the extension pipe 5A is fully extended, the suction port body 6, the extension pipe 5A, and the cleaner body 3 are integrally removed from the storage base 31A, thereby extending the extension pipe 5A.
