The dust collecting meter 15 has a transparent cylindrical body 19.
When the intake side of the electric blower 6 becomes a negative pressure due to an increase in the amount of dust collected in the dust collection chamber 9, the hands 21 are opposed to the urging force of the springs 20. Vent holes formed in the rear wall 16 of the storage room 14 by moving to the electric blower storage room 7 side
The outside air sucked into the storage chamber 14 via 17 is guided to the intake side of the electric blower 6 to prevent the electric blower 6 from being overspeeded.

Reference numeral 22 denotes a handle rotatably supported by the cleaner main body 1 and is housed in a groove 23 formed in the upper surface of the rear part of the cleaner main body 1. The handle 22
Has a substantially triangular cross section, and the lower surface in the storage state in the concave groove 23 is formed in an arc shape. As shown in FIG.
22 is formed in a shape that is easy to fit in the hand. As shown in FIGS. 8 and 9, the handle 22 is configured to form a gap between the handle 22 and the bottom surface of the groove 23 when housed in the groove 23. The outside air is efficiently guided from the handle raising notch 24 to the ventilation hole 17 through the gap between the handle 22 and the concave groove 23.

Numeral 25 denotes a pair of projections formed at the rear of the lower case 3 of the cleaner main body 1, and numeral 26 denotes a leg mounted on the rear of the upper case 2 of the cleaner main body 1. Thereby, the cleaner main body 1 is held in an upright state. Reference numeral 27 denotes an insertion portion which is formed by hanging from both sides of the lower surface of the leg portion 26. The insertion portion 27 is adapted to be inserted and fixed in a screw hole 4 for fixing the upper case 2 and the lower case 3 with a screw 5, and the width of the insertion portion 27 in the front-rear direction. Is formed to have substantially the same size as the diameter of the screw hole 4,
The rotation of the leg 26 around the center is prevented. Reference numeral 28 denotes an L-shaped rib formed on the rear side of the insertion portion 27 toward the center from the insertion portion 27. The L-shaped rib 28 covers the screw hole 4. 29 is the leg 26
A pair of engaging portions formed on a rib 30 hanging down from the front edge engage with a locking portion 32 formed on a locking wall 31 of the upper case 2. Also, the rib 30 of the leg 26
Is held between the locking wall 31 and the locking rib 33 of the upper case 2 to prevent the engagement between the engaging portion 29 and the locking portion 31 from being released.

Reference numeral 34 denotes an attachment storage portion formed between the upper case 2 and the leg portion 26. An attachment 35 detachably attached to the extension tube 12 in place of the floor suction tool 13.
Is detachably stored. 36 is the leg
26, the attachment rib 34
The attachment 35 stored in the attachment 35 is held to prevent the attachment 35 from accidentally falling off. Numeral 37 denotes a blocking rib formed on the leg portion 26, which comes into contact with a narrow portion of the attachment 35 stored in the attachment storage portion 34 and prevents the attachment 35 from rotating. Numeral 38 denotes a covering rib hanging down from the leg 26 so as to cover an engaging portion between the upper case 2 and the leg 26 and the like.

As shown in FIG. 1, when the insertion portion 27 is inserted into the screw hole 4 from above and pushed downward, as shown in FIG. 1, the insertion portion 27 is inserted into the screw hole 4 and Joint 29
Engages with the locking portion 32 and is fixed to the cleaner body 1. When not in use, the cleaner body 1 is held upright by the projections 25 and the legs 26.

When the attachment 35 is not used, the attachment 35 is stored and held in the attachment storage section 34. In the state where the attachment 35 is stored and held in the attachment storage portion 34, the attachment 35 is securely held and held between the holding rib 36 and the upper case 2 by the elastic force of the leg portion 26, and the attachment 35 is inadvertently dropped from the attachment holding portion 34. Is prevented, and a blocking rib 37 abuts on a narrow portion of the attachment 35 to prevent the attachment 35 from rotating.

Attachment storage section for attachment 35
Attach and remove the legs 26 to the vacuum cleaner body 1
The force is applied in the direction to remove from the
, The insertion of the insertion portion 27 into the screw hole 4, and the contact of the rib 30 with the locking wall 31 prevent the leg portion 26 from slipping upward, and the leg 26 Since the width in the direction is substantially the same as the diameter of the screw hole 4 and the rib 30 is locked between the locking wall 31 and the locking rib 33 of the upper case 2, the leg 26 is inserted. Rotation around the part 27 is prevented, so that the engagement between the locking part 32 and the engaging part 29 can be securely held,
The legs 26 can be prevented from falling off from the cleaner body 1.

[0021]

According to the first aspect of the present invention, since the legs are formed as separate parts from the cleaner body, the structure of the mold for molding the cleaner body can be simplified. Also,
Since the screw holes for screw-fixing the upper case and the lower case constituting the cleaner main body are covered with the legs, it is possible to improve the appearance of the cleaner main body.

According to the configuration of the second aspect of the present invention, since the legs are formed as separate parts from the cleaner body, the structure of the mold for molding the cleaner body can be simplified. In addition, the legs can be attached using screw holes for screwing the upper case and the lower case constituting the cleaner body, and the mounting structure of the legs can be simplified, and Thus, the screw holes can be covered and concealed, so that the external appearance of the cleaner body can be improved.

According to the third aspect of the present invention, since the leg is formed as a separate part from the cleaner body, the structure of the mold for molding the cleaner body can be simplified. Further, the legs can be securely fixed by using screw holes for screwing the upper case and the lower case constituting the cleaner body, and the screw holes can be covered and hidden by the legs, There are effects such as the appearance of the cleaner body can be improved.
