BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having a stand storage function for storing a vacuum cleaner body in an upright state.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 4-30821, there is known an electric vacuum cleaner having a stand storing function for storing a cleaner body in an upright state. The vacuum cleaner is in normal use, that is, the bellows hose
Since the hook formed on the extension pipe on the floor suction tool side (second extension pipe) is engaged with the recess of the cleaner body for simple storage with the extension pipe of the book connected, There is a drawback that the height dimension becomes large.

Therefore, the first extension pipe and the second extension pipe are disconnected from each other, the hook of the second extension pipe is engaged with the recess of the cleaner body, and the first extension pipe is connected with the floor suction tool. It is conceivable that the provided locking portion is configured to be engaged with the engaging portion provided on the second extension pipe to be housed.

However, with this structure,
A force may be applied to the first extension pipe or the bellows hose, and the first extension pipe may be twisted with respect to the second extension pipe, and the locking portion of the first extension pipe and the engagement portion of the second extension pipe may be damaged. there were.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks. The height dimension when the stand is housed can be reduced, and the extension pipe or the like is damaged even when a force is applied to the extension pipe or the like. It is an object to provide a vacuum cleaner that does not.

[0006]

According to the present invention, there is provided a cleaner body having a suction port at a front portion thereof and a recess formed therein, a hose detachably connected to the suction port, and a hose detachably attached to the hose. A first extension pipe connected to the first extension pipe, and a second extension pipe detachably connected to the first extension pipe and having a suction tool attached to the other end,
The second extension pipe is formed with a hook that fits into a recess of the cleaner body, and an engaging portion that engages with an engagement portion formed on the first extension pipe. The diagonal dimension of the portion locked by the engaging portion is substantially equal to the width of the engaging portion or smaller than the width of the engaging portion.

Further, according to the present invention, a cleaner body having a suction port at a front portion and having a recess, a hose detachably connected to the suction port, and a hose detachably connected to the hose. A first extension pipe and a second extension pipe detachably connected to the first extension pipe and having a suction tool attached to the other end thereof are provided, and the second extension pipe is fitted in a recess of the cleaner body. With a matching hook,
An engaging portion with which an engaging portion formed on the first extension pipe engages, and both lower corners of the engaging portion are engaged with the engaging portion of the engaging portion. It is characterized in that it is formed in an arc shape having a radius substantially equal to the width of the engaging portion or smaller than the width of the engaging portion, with a position facing the corner diagonally as the center.

Further, the present invention has a suction port at the front,
A cleaner body having a recess, a hose detachably connected to the suction port, a first extension pipe detachably connected to the hose, and a detachable connection to the first extension pipe, A second extension pipe to which a suction tool is attached at the other end;
The extension pipe is formed with a hook that fits into the recess of the cleaner body and an engaging portion that engages with the engaging portion formed on the first extension pipe, and the engaging portion has a narrow space. A portion, an expanding portion, and an elastic portion that urges the locking portion toward the narrow portion,
When the second extension pipe is rotated with respect to the first extension pipe,
It is characterized in that a guide portion for guiding the locking portion to the expansion portion is formed.

[0009]

According to the structure of claim 1 of the present invention, when not in use, the connection between the first extension pipe and the second extension pipe is disconnected, and the hook of the second extension pipe is engaged with the recess of the cleaner body. ,
The locking portion of the first extension pipe is locked in the engagement portion of the second extension pipe and stored. In this stored state, when a force is applied to the first extension pipe or the hose and the first extension pipe acts on the second extension pipe so as to twist, the diagonal dimension of the portion locked by the locking portion of the engaging portion Is approximately the same as the width of the engaging portion or smaller than the width of the engaging portion, so that the engaging portion and the engaging portion are disengaged from each other, and the engaging portion and the engaging portion are prevented from being damaged.

According to the second aspect of the present invention,
When not in use, disconnect the connection between the first extension pipe and the second extension pipe, engage the hook of the second extension pipe with the recess of the cleaner body, and attach the first extension pipe to the engaging portion of the second extension pipe. The locking part of is locked and stored. In this stored state, when a force is applied to the first extension pipe and the hose and the first extension pipe is twisted with respect to the second extension pipe, both lower corners of the locking portion are engaged with the engagement portion of the locking portion. Since the width of the engaging portion is formed to be substantially equal to or smaller than the width of the engaging portion around the position where the lower corner of the engaged portion is diagonally opposed, the engagement portion and the engaging portion are formed. This prevents the engagement and locking parts from being damaged.

Further, according to the third aspect of the present invention, when not in use, the connection between the first extension pipe and the second extension pipe is disconnected, and the hook of the second extension pipe is engaged with the recess of the cleaner body. At the same time, the engaging portion of the second extension pipe is locked with the locking portion of the first extension pipe to be housed. In this stored state, when a force is applied to the first extension pipe and the hose and the first extension pipe twists with respect to the second extension pipe, the engaging portion resists the biasing force of the elastic portion and the expanding portion. The engaging portion and the engaging portion are disengaged from each other, and the engaging portion and the engaging portion are prevented from being damaged.
