When the gap suction pipe 18 is inserted into the connection opening 21 of the cleaner body 10, the engagement protrusion 23 of the grip 22 becomes a locking mechanism that engages with the attachment recess 20 of the gap suction pipe 18. By the locking mechanism, the engaging projection 23 is locked to the mounting recess 20, and the gap suction tube 18 is held by the cleaner body 10. Further, the lock lever 22 is unlocked by pressing the release lever 24 provided on the upper surface of the cleaner body 10.

In Figs. 3 and 5, the suction port 25 of the floor inhalation device 19 sucks. The floor side suction passage 26 through which the dust is introduced is connected to the opening hole 27 of the dust collecting portion 15 via the common flow path 31 to be described later by the suction port 25 of the floor suction device 19 as indicated by the direction of the arrow mark.

On the other hand, the suction pipe side suction flow path 28 through which the dust sucked by the gap suction pipe 18 passes is connected to the connection pipe 30 and the common flow path 31 to be described later via the gap suction pipe 18 and the connection pipe 30 and the later-described common flow path 31. The opening holes 27 of the dust collecting portion 15 are in communication. That is, the connection pipe 30 is provided between the gap suction pipe 18 and the common flow path 31, and communicates with the gap suction pipe 18 and the common flow path 31.

Then, in the cleaner body 10, the common flow path 31 which is a path which merges both the floor side suction flow path 26 and the suction pipe side suction flow path 28 is provided.

In FIGS. 5 and 6, a hole 33 communicating with the hole 32 of the connection pipe 30 is formed in the cleaner body 10 in the vicinity of the common flow path 31, and the flow path in the communication pipe 30 communicates with the common flow path 31.

Further, as shown in FIGS. 2 and 6, the connecting pipe 30 is formed with claws 34. The claws 34 are fitted to a locking portion (not shown) formed on the inner wall surface of the hole 33 of the cleaner body 10, whereby the connecting tube 30 is configured to be detachable from the hole 33 of the cleaner body 10.

In the above-described configuration, the dust sucked by the suction port 25 of the floor suction device 19 through the floor side suction passage 26 or the dust sucked by the gap suction pipe 18 through the suction pipe side suction passage 28 is blocked in the vicinity of the common flow path 31. Therefore, it is not necessary to remove the dust collecting portion 15 or the floor suction device 19 from the cleaner body 10, and the connecting pipe 30 is removed from the cleaner body 10, whereby it can be taken out by the hole 33 provided in the vicinity of the common flow path 31. Common flow path 31 or its attached Nearly obstructed dust. Therefore, the dust can be removed without labor, and the dust removal operation becomes easy.

In the above description, the hole 33 that communicates with the connecting pipe 30 is disposed in the vicinity of the common flow path 31. However, as shown in FIG. 5, the hole 33 may be provided in the floor side suction flow path 26 and the suction pipe side. The flow path 28 is located at a right obliquely upper side of the junction point merged in the common flow path 31 as a particularly more effective arrangement. That is, the hole 33 communicating with the connection pipe 30 may be provided at a position avoiding the above-described junction point in the common flow path 31. In this way, the hole 33 can be disposed by avoiding the turbulent flow portion from the merge point of the airflows at different paths, thereby suppressing the phenomenon of dust clogging.

Further, even if the dust passing through the suction pipe side suction passage 28 is temporarily blocked, since the hole 33 is provided at the right oblique upper side of the joining point of the airflow in the common flow path 31, the blocked dust remains only on the right oblique upper side. The dust attracted by the suction port 25 of the floor suction device 19 can be secured to the lower left side in the common flow path 31 through the flow path. Therefore, it is possible to avoid the so-called worst phenomenon in which both the floor side suction flow path 26 and the suction pipe side suction flow path 28 are blocked by dust and cannot be attracted.

Further, as shown in FIG. 5, the diameter 38 (flow path cross-sectional area) of the flow path in the common flow path 31 is made larger than the diameter of the other floor side suction flow path 26 or the diameter of the suction pipe side suction flow path 28. . According to this configuration, since the volume of the space in the common flow path 31 can be ensured, the flow velocity of the airflow including the dust flowing into the common flow path 31 is lowered. Therefore, when a large coarse dust is sucked in, etc., large coarse dust is secured in the common flow path 31 in which the flow rate is lowered. As a result, dust clogging in other places can be prevented, and maintenance at the time of clogging can be more easily performed.

Further, as shown in Fig. 6, the diameter 39 of the connecting pipe 30 in the downstream side (hole 32 side) of the suction airflow flowing in the L-shaped connecting pipe 30 is set to be larger than the upstream side of the suction air flow (hose) The diameter of the connecting pipe 30 in the 29 side is large. In this manner, the connecting pipe 30 is configured to gradually increase in diameter in the direction in which the suction airflow advances. Thereby, it is possible to prevent dust from being clogged in the connecting pipe 30, particularly in the slightly L-shaped bent portion 35.

In addition, in FIG. 2 and FIG. 3, the connection pipe 30 is disposed in the lower rear portion of the cleaner body 10, whereby when the user removes the gap suction pipe 18 from the cleaner body 10, the distance A from the floor to the connection pipe 30 becomes shorter. . As a result, the increased torque of the connecting pipe 30 becomes small, the stability of the standing state of the cleaner body 10 is improved, and it becomes difficult to fall over, and the usability is improved.

Moreover, in FIG. 3, the connection pipe 30 is formed in the L direction of the longitudinal direction of the cleaner body 10, and the opening part 36 connected with the hose 29 is the upper direction of the cleaner body 10. Thereby, the range of the rotation of the hose 29 is suppressed, and the improvement of the bending durability of the hose 29 is improved.

Suck The pipe side suction flow path suction pipe is connected to the dust collecting portion via the common flow path. The connecting pipe is disposed between the gap suction pipe and the common flow path, and communicates with the gap suction pipe and the common flow path. A hole that communicates with the connection pipe in the vicinity of the joining position of the floor side suction flow path and the suction pipe side suction flow path in the common flow path is provided in the cleaner body, and the connection pipe is detachably provided in the hole of the cleaner body.

Therefore, when dust is accumulated in the common flow path, the suction flow path of the floor suction device, and the suction flow path of the gap suction pipe, the connection pipe can be removed from the cleaner body, whereby the dust removal operation in the vicinity of the common flow path becomes easily.

Further, in the vertical vacuum cleaner of the present invention, the hole communicating with the connecting pipe is provided at a position avoiding the joining point of the floor side suction flow path and the suction pipe side suction flow path in the common flow path.

Thereby, the turbulent flow of the airflow from the different paths at the merge point can be avoided, and the phenomenon of dust clogging can be suppressed. Further, even if the dust from the suction pipe side suction passage is temporarily blocked, since the hole is provided obliquely upward toward the right at the joining point, the blocked dust remains only on the right oblique upper side, thereby ensuring the lower left side in the common flow path. The passage through which the dust attracted by the suction port of the floor suction device can pass. As a result, it is possible to avoid the worst phenomenon in which both the floor side suction flow path and the suction pipe side suction flow path are blocked by dust and are not attracted.

Further, in the vertical vacuum cleaner of the present invention, the diameter of the flow path in the common flow path is made wider than the diameter of the floor side suction flow path that communicates with the common flow path and the diameter of the suction pipe side suction flow path.

Thereby, the volume within the wider common flow path can be ensured In the meantime, the flow rate of the airflow including the dust entering the common flow path can be reduced, and when a large coarse dust is sucked, the dust can be secured in the common flow path in which the flow rate is lowered. As a result, dust clogging in other places can be prevented, and maintenance in dust clogging can be easily performed.

Further, in the vertical vacuum cleaner of the present invention, the connecting pipe that communicates with the gap suction pipe forms a claw, and the claw is detachably engaged with the hole of the cleaner body, and the connecting pipe is disposed at the lower rear portion of the cleaner body.

Thereby, the distance from the ground to the connecting pipe can be shortened, and when the user uses the gap suction pipe, the standing state of the vertical vacuum cleaner body is stable and difficult to fall, thereby improving the usability.

Further, in the vertical type electric vacuum cleaner of the present invention, the connecting pipe that communicates with the gap suction pipe is formed in a slightly L shape, and the connecting pipe in the downstream side of the suction airflow flowing in the L-shaped connecting pipe The caliber is set to be larger than the diameter of the connecting pipe in the upstream side of the suction airflow, and the diameter is gradually widened in the direction in which the suction airflow advances. Thereby, it is possible to prevent dust from clogging in the connecting pipe, particularly in the slightly L-shaped bent portion.

As described above, the present invention has a detachable connecting pipe and can easily perform dust clogging removal work, so that it is easy to use and can be widely applied to a vertical electric vacuum cleaner.
