DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates an auxiliary suction device in a main body.
The present invention relates to an electric vacuum cleaner .

[0002]

2. Description of the Related Art Conventionally, an auxiliary suction device, such as a suction device for a gap or a suction device for a shelf, which is connected to a hose or an extension pipe according to a cleaning place, is integrally housed in a main body of the vacuum cleaner.
Will be described . That is, a concave portion is formed on the outer peripheral surface of the upper body constituting the main body containing the fan motor, and an auxiliary suction device such as a suction device for a gap or a suction device for a shelf is inserted into the recess, and the cover is rotatable with the lid. Open / closed.

[0003]

However, in this structure, if there is a clearance between the recess and the auxiliary suction device, the auxiliary suction device similarly vibrates due to the vibration during the operation of the main body, and the clearance between the auxiliary suction device and the auxiliary suction device. It produces abnormal sounds due to contact,
If the auxiliary suction tool is pressed into the recess and stored, the auxiliary suction tool cannot be easily taken out when it is taken out, or the auxiliary suction tool is damaged.

[0004] The present invention solves this problem and provides an auxiliary suction device.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

1 to 4, a main body 1 of a vacuum cleaner is shown.
Has a dust-collecting chamber 3 in the front for accommodating a dust-collecting bag 2 for filtering and accumulating dust sucked through a floor suction tool, an extension pipe, and a hose (not shown), and an electric blower 4 and a cord in the rear. It has a drive chamber 5 containing a winding device and the like. A front cover 6 is attached above the dust collection chamber 3 and covers the dust collection chamber 3 so that it can be opened and closed. The front part of the front lid 6 is rotatably fixed to the upper body 7 at the rear part, and the front part is held by the upper body 7 by the locking action of the buckle claw 8. A dust collection amount display device 9 is attached to a substantially central portion of the upper main body 7, and is covered with an upper lid 10. Top lid 1
The upper side of the dust collecting quantity display device 9 0 window hole 11 is formed,
The movement of the green pointer A13 and the red pointer B14, which are integrally displaced in the pointer cylinder 12 in response to the vacuum pressure in the dust collection chamber 3 reduced by the accumulation of dust, can be visually recognized from outside the main body 1.

The drive chamber 5 is formed by fastening the upper body 7 and the lower body 15 to each other using a fastening screw. The electric blower 4 having the vibration-proof rubber A16 and the vibration- proof rubber B17 mounted on the front and rear end surfaces thereof is disposed in the drive chamber 5 with the vibration-proof rubber A16 and the vibration- proof rubber B17 being sandwiched between the upper body 7 and the lower body 15. You.
The intake dust-containing air sucked into the main body 1 by the operation of the electric blower 4 is filtered and sucked by the dust collection bag 2 to become clean air, and the upper main body 7 and the lower main body 15 are provided behind the drive chamber 5.
The gas passes through an exhaust grid A18 and an exhaust grid B19 formed integrally with the main body 1 and is discharged out of the main body 1. Reference numeral 20 denotes a storage recess formed immediately below the exhaust grid B19, and the clearance suction tool 21 is stored with its longitudinal direction substantially parallel to the floor surface. The rear of the lower body 15 is formed using a cavity mold 22 which is a fixed mold of the resin injection mold, and a movable core mold 23 and a side core mold 24.
Are simultaneously formed by a side core mold 24 that is laterally punched with respect to the cavity mold 22 and the core mold 23 that forms the exhaust grid B19 . Therefore, there is no gap in the storage recess 20.
An opening into which the longitudinal direction of the suction tool 21 can be inserted is formed.
The opening is formed on the rear surface of the lower body 15.

Reference numeral 25 denotes a holding claw having resin elasticity formed on the lower end of the storage recess 20 , that is, on the lower surface on the opening side of the storage recess 20 by the die cutting structure of the cavity mold 22 and the side core mold 24. When the suction tool 21 for the gap is inserted into the storage recess 20, the holding claw 25 is inserted into the suction tool 21 for the gap.
Hook on the lower outer peripheral surface of the connecting cylindrical portion 26 to be fitted and connected to the hose or the extension pipe of the above, so that the gap suction tool 21 falls out of the storage recess 20 or vibrates in the storage recess 20 during use of the main body 1. Has been prevented. The cavity mold 2
2 and side core mold 24
Therefore, the lower surface of the storage recess 20 is formed by a cavity mold.
A hole is formed.

Numeral 27 denotes a swivel wheel rotatably mounted substantially at the center of the lower surface of the dust collecting chamber 3. A vacuum cleaner is used together with a pair of wheels 28 rotatably held on both rear side surfaces of the lower body 15. The movement of the main body 1 inside is facilitated.

Next, the operation and operation of the above configuration will be described. When cleaning a narrow groove or a narrow gap such as a rail surface of an aluminum sash while using the vacuum cleaner, take out the gap suction tool 21 mounted and stored in the storage recess 20 and remove it with a hose or the like. Use by connecting to the end of the extension tube. At this time, the holding claw 25 having elasticity is warped and deformed to the floor surface side to lightly pass through the connection cylindrical portion 26, so that the clearance suction tool 21 can be taken out with a light pulling force. After use, the gap suction tool 21 is removed from the end of the hose or extension tube and inserted into the storage recess 20 as before, so that the elastic holding claw 25
However, once the warp is deformed toward the floor side, the connecting cylindrical portion 26 of the gap suction device 21 is passed through the storage concave portion 20, and then hooked to the lower outer peripheral surface of the connection cylindrical portion 26 to form the gap suction device 2.
1 is securely held in the storage recess 20.

By the way, in the state of being stored in the storage recess 20, the entire weight of the gap suction tool 21 is supported by the lower surface of the storage recess 20, so that no weight load acts on the holding claw 25 and the elasticity is deteriorated. The gap suction tool 21 is securely held without any gap. At the same time, the holding claw 25 is hooked to the connection cylindrical portion 26 by elastic force, so that the suction device 21 for the gap is
There is no vibration inside.

When using the suction device 21 for a gap,
It can be immediately removed with a lighter pull-out force than the storage recess 20, and after use it can be stored simply by inserting it into the storage recess 21 with a light pressing force.
No damage to 0.

[0015]

As described above, according to the present invention, the rear of the main body is provided.
Has its longitudinal direction substantially parallel to the floor surface, and
An opening is provided in the storage recess to store the auxiliary suction tool.
Since it is provided, it eliminates accumulation of dust etc. in the storage recess, and
A lid that covers the conventional auxiliary suction tool is no longer necessary,
The removal of the auxiliary suction device is good, and the
While securely holding the auxiliary suction tool in the storage recess.
When the auxiliary suction device is used, it can be attached and detached with a small operation force, and when it is used, the attachment and detachment operation can be performed immediately, so that the usability is improved. In addition, mold
Since a hole is formed by the tee mold,
Dust can be dropped from the hole,
The cleanability of the part is good.
