The extension tube 19 is connected to the distal end side of the hose 17 opposite to the grip tube 18. The extension pipe 19 is located upstream of the suction air passage with respect to the grip pipe portion 18. In the present embodiment, the extension pipe 19 is a telescopic extension pipe, but is not limited to this, and may be a non-telescopic extension pipe 19, an extension pipe 19 in which a plurality of pipe bodies are connected to each other, or the like. In the present embodiment, the extension pipe 19 and the grip pipe 18 constitute the second pipe 28 in the present embodiment.

In the present embodiment, an example in which the second pipe portion is constituted by the grip pipe portion 18 and the extension pipe 19 has been described, but the structure of the second pipe portion is not limited to this, and other structures such as a structure in which the second pipe portion is constituted by 1 pipe portion, a structure in which the second pipe portion is constituted by 3 or more pipe portions, and a structure in which a part thereof includes a hose may be employed. The structure of each tube portion such as the grip tube portion 18 is not limited to the above example. The second pipe portion is not particularly limited as long as it is connected between the suction port body 20 and the hose 17.

The suction port body 20 is connected to the distal end side of the second tube portion 28 opposite to the holding tube portion 18 with respect to the extension tube 19. The suction port body 20 is located upstream of the extension pipe 19 in the suction air passage and constitutes an upstream end of the suction air passage. In the present embodiment, the suction body 20 is a floor brush, and the floor brush includes: a laterally long housing 30; and a suction port body connection pipe 31 protruding from the casing 30, but is not limited thereto, and any type of suction port body 20 may be used.

Here, the locking portion 33 shown in fig. 1, 2, 4(a) and 4(b) is a pocket portion into which the locked portion 34 is inserted. The locking portion 33 is disposed at a lower portion of the cleaner body 2, which is a position facing the surface to be cleaned. The locking portion 33 is disposed at a lower portion of the front side in the traveling direction of the cleaner body 2. In the present embodiment, the locking portion 33 is disposed below the dust collecting portion 6 in the cleaner body 2. The locking portion 33 is disposed at the center in the width direction of the cleaner body 2. The locking portion 33 is disposed in front of the front wheel 10.

Further, the locking portion 33 includes: a recess 38 recessed in the cleaner body 2; and a locking projection 39 provided to project from the recess 38. The recess 38 is formed along the front-rear direction of the cleaner body 2. The recess 38 in this embodiment is located at the forefront of the lower part of the cleaner body 2. The recess 38 has a groove shape with an open front end. In the present embodiment, the recess 38 does not have a structure in a projected range of the locked portion 34 at one end side in the insertion direction with respect to the locking portion 33, that is, forward, and the opening end is exposed upward in the vacuum cleaner body 2 in the standing state. The open end of the recess 38 is located at the inclined portion 36. The locking projections 39 are formed in a rib shape along both side edges of the recess 38. The locking projection 39 includes an introduction portion 40, and the introduction portion 40 is inclined so as to be opened toward one end side of the portion to be locked 34 with respect to the insertion direction of the locking portion 33, that is, toward the front. The locking projection 39 is formed to be flush or substantially flush with the lower portion (the inclined portion 36) of the cleaner body 2, and is disposed to be separated downward from the top surface portion 41 of the recess 38.

The locked portion 34 is a hook portion that is inserted and locked to the locking portion 33. The engaged portion 34 is formed in the extension pipe 19. In the present embodiment, the engaged portion 34 is provided in the extension pipe 19, but is not limited to this, and may be provided in another portion of the air passage body 7 such as the suction port body connection pipe 31 of the suction port body 20. The locked portion 34 is disposed at a position close to the front end of the suction port body 20, and is set to have a distance from the front end of the suction port body 20 smaller than a distance from the rear end of the rear wheel 11 to the locking portion 33. As shown in fig. 4(a) and 4(b), the engaged portion 34 includes: an inserted portion 43 inserted between the recess 38 of the locking portion 33 and the locking protrusion 39; and a groove portion 44 into which the locking protrusion 39 is fitted. The inserted portion 43 is formed in a linear rib shape and is disposed adjacent to the groove portion 44. The groove 44 is formed in a linear groove shape and is formed to be opened toward the open end, i.e., the distal end.

Next, an operation of the embodiment will be described.

When cleaning, the user operates the setting means of the setting unit 25 while gripping the grip 26 of the grip pipe portion 18, thereby activating the electric vacuum cleaner 1. The user moves the cleaner body 2 to a desired position by the traveling mechanism 4, operates the air passage body 7 by the grip 26, and sucks dust and air into the suction air passage by the negative pressure generated by the driving of the electric blower 3 while moving the suction port body 20 located at the tip on a surface to be cleaned such as a floor surface. The dust-containing air is sucked into the dust collecting section 6 from the suction port 5, the dust is separated and collected in the dust collecting section 6, and the air is sucked into the electric blower 3, and the air cools the electric blower 3 and is discharged to the outside of the cleaner body 2 from the exhaust port 14. When the cleaning is completed, the user operates the setting means of the setting unit 25 to stop the electric vacuum cleaner 1.

When the electric vacuum cleaner 1 is stored, first, when the front side of the suction port 5 side of the cleaner body 2 is raised on a flat ground surface S such as a floor surface by the air passage body 7, the cleaner body 2 is rotated around the rear wheels 11, and as shown in fig. 2, in a state where the support portion 15 is in contact with the ground surface S, the cleaner body 2 is supported on the ground surface S in an upright state where the front side of the suction port 5 side is an upper side and the rear surface portion 12 side which is the opposite side thereof is a lower side. In this standing state, the open end of the recess 38 of the locking portion 33 is exposed upward of the cleaner body 2, and the locking portion 33 is inclined at a predetermined angle with respect to the vertical direction. Further, the center of gravity of the cleaner body 2 is located closer to the cleaner body 2 than a virtual line V in the vertical direction passing through the center of the rear wheel 11 shown in fig. 1, as viewed in the vertical direction. The locking portion 33 is located on the opposite side of the cleaner body 2 from the virtual line V and close to the virtual line V.

Next, the user retracts the extension pipe 19, and simultaneously winds the hose 17 of the extension pipe 19, as shown in fig. 4(a) and 4(b), the locked portion 34 is inserted into the locking portion 33 from above with respect to the upright cleaner body 2, the inserted portion 43 is fitted into the recess 38, and the locking protrusion 39 is fitted into the groove portion 44. At this time, since the open end of the recess 38 of the locking portion 33 is exposed upward, the user can easily align the locked portion 34 with the locking portion 33 while visually observing the position of the open end of the recess 38 of the locking portion 33. Further, since the opening end of the recess 38 is positioned at the inclined portion 36, the inclined portion 36 serves as a guide for guiding the portion to be locked 34 to the locking portion 33 in the locking portion 33. Further, since the portion to be locked 34 is introduced between the locking projections 39 on both sides by the introduction portion 40, the portion to be locked 34 can be guided to a standard position with respect to the locking portion 33 even if the positions of the locking portion 33 and the portion to be locked 34 are slightly shifted in the left-right direction. Further, since the opening end of the groove portion 44 of the engaged portion 34 is opened, the engaging projection 39 can be easily inserted into the groove portion 44. When the engaged portion 34 is inserted into the engaging portion 33, as shown in fig. 1, the extension tube 19 of the air passage body 7 is held in an inclined state along the opening direction of the recess 38, that is, the inclined direction of the inclined portion 36, and is self-standing while being held in the cleaner main body 2.

At this time, the grip pipe portion 18 located on the downstream side of the suction air passage with respect to the base end side of the extension pipe 19 of the air passage body 7 is located on the cleaner main body 2 side with respect to the virtual line V. In the example shown in fig. 1, in a state where the locked portion 34 is locked to the locking portion 33, at least the connection position of the second tube portion 28 and the hose 17, that is, the connection portion 24 is positioned on the cleaner body 2 side with respect to the virtual line V. In the air passage body 7, the excess half portion of the hose 17, the entire grip pipe portion 18, and the base end side of the extension pipe 19 are positioned on the cleaner body 2 side with respect to the virtual line V, and the portion of the hose 17 wound around the extension pipe 19, the portion from the center portion to the tip end side in the longitudinal direction of the extension pipe 19, and the entire suction port body 20 are positioned on the opposite side of the cleaner body 2 with respect to the virtual line V in a state where the locked portion 34 is locked to the locking portion 33. The inclination θ of the extension pipe 19 in the axis a direction with respect to the virtual line V is preferably 10 ° or more, and in the present embodiment, is about 12.5 °.

Here, since the rear wheel 11 of the vacuum cleaner body 2 in the standing state is rotatable with respect to the vacuum cleaner body 2, it is easy to rotate around the rear wheel 11, and if most of the weight of the air path body 7 is applied to the opposite side of the vacuum cleaner body 2 with respect to the virtual line V, the gravity center position of the electric vacuum cleaner 1 as viewed in the vertical direction is deviated from the virtual quadrangle SQ (fig. 3) to the air path body 7 side, whereby the whole electric vacuum cleaner 1 may easily tilt toward the air path body 7 side, whereas in the present embodiment, a part of the weight of the air path body 7 is applied to a position closer to the vacuum cleaner body 2 side than the center of the rear wheel 11, and therefore, the gravity center position of the electric vacuum cleaner 1 as viewed in the vertical direction converges into the SQ quadrangle, and the vacuum cleaner body 2 can be compactly stored in the standing state, the electric vacuum cleaner 1 has improved stability and is less likely to fall down, and the virtual quadrangle SQ is a range surrounded by the ground contact position of the rear wheel 11 with respect to the ground contact surface S and the ground contact position of the center portion of the support portion 15 or with respect to the ground contact surface S.

In particular, in recent years, the size of the cleaner body 2 has been reduced, and therefore, the supporting position of the cleaner body 2 with respect to the ground surface S by the rear wheels 11 and the supporting portion 15 has come close to each other, that is, the virtual quadrangle SQ has become small, and the supporting stability of the cleaner body 2 in the standing state may be impaired. In the present embodiment, in the locked state in which the air passage body 7 is locked to the locking portion 33 of the cleaner body 2 by the locked portion 34, a part of the weight of the air passage body 7 is distributed to the cleaner body 2 side with respect to the virtual line V, and thus, the center of gravity position of the electric vacuum cleaner 1 in the locked state can be prevented from being displaced, and the arrangement can be stably performed even when the cleaner body 2 is downsized.

In addition, since the grip pipe portion 18 is also positioned on the cleaner body 2 side with respect to the virtual line V in the state where the locked portion 34 is locked to the locking portion 33, a part of the weight of the air passage body 7 can be reliably applied to the cleaner body 2 in a direction in which the electric vacuum cleaner 1 is prevented from falling down.

In addition, since the setting portion 25 connected to the grip portion 26 is also positioned on the cleaner body 2 side with respect to the virtual line V in the state where the locked portion 34 is locked to the locking portion 33, the weight of the air passage body 7 applied to the cleaner body 2 in the direction in which the electric vacuum cleaner 1 is prevented from falling down can be further increased.

In addition, in a state where the locked portion 34 is locked to the locking portion 33, the connection position of the grip pipe portion 18 and the extension pipe 19 is located on the cleaner body 2 side with respect to the virtual line V, and therefore, the weight of the air passage body 7 applied to the cleaner body 2 in a direction in which the electric vacuum cleaner 1 is prevented from falling down can be further increased.

Further, since the portion to be locked 34 and the suction port body 20 are disposed close to each other, the suction port body 20 does not contact the ground surface S in a state where the portion to be locked 34 is locked to the lock portion 33, and therefore, when the portion to be locked 34 is locked to the lock portion 33, there is no case where the suction port body 20 at a position closer to the ground surface S than the portion to be locked 34 contacts the ground surface S to prevent the portion to be locked 34 from being inserted into the lock portion 33, and the like, and the locking workability is good, and the ground surface S is less likely to be soiled by the suction port body 20. Even when the dust collector main body 2 is about to fall down by applying an external force or the like to the dust collector main body 2 and the air passage body 7, the suction port body 20 can be supported in a state of being less likely to fall down by being supported on the ground surface S.

Although several embodiments of the present invention have been described, these embodiments are provided as examples, and are not intended to limit the scope of the present invention. These new embodiments may be implemented in various other forms, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. These embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
