It may be arranged, or a plurality of functional parts may be arranged on one surface part 20 . The contact portion 15 may be formed in a block shape, or may be formed in a hollow shape having a contact surface 19 and a surface portion 20 .

Next, operation of the first embodiment will be described.

When cleaning, for example, when cleaning a portion to be cleaned such as a floor surface, the user grips the grip portion 12 . Next, as shown in FIG. 4, the user places the vacuum cleaner 1 in a use posture with the body connection port 3 facing downward. In this use posture, the other end side of the air passage body 5 is directed toward the part to be cleaned. Next, the user activates the vacuum cleaner 1 by operating the setting means 13 . The electric vacuum cleaner 1 sucks dust together with air from the suction port 7 or the like that moves along the part to be cleaned by the operation of the grip part 12 by the user, using the negative pressure generated by driving the electric blower 8 . Dust-containing air is sucked into the dust collecting section 10 from the suction air passage of the air passage body 5 via the main body connection port 3 . The dust collection unit 10 separates and collects dust from the dust-containing air. The air from which the dust has been separated by the dust collector 10 is discharged from the dust collector 10 and sucked into the electric blower 8 . The air sucked into the electric blower 8 cools the electric blower 8 and then is exhausted to the outside of the cleaner body 2 through the exhaust port 4 .

When the electric vacuum cleaner 1 is not used, the electric vacuum cleaner 1 can be stored in a room, a corner of furniture, or the like. As shown in FIGS. 1 and 3, the user places the suction port body 7 on the floor with the longitudinal direction of the vacuum cleaner 1 along the vertical up-down direction, and touches the contact portions 15 on both sides. The contact surface 19 is brought into contact with the installation portions 22 that intersect each other, such as two walls forming a corner of a room. The vacuum cleaner 1 is supported by the suction port body 7 and the abutting portions 15 on both sides at three points with respect to the floor surface and the installation portions 22 on both sides, and is self-supporting without being leaned against the installation portions 22. can be made

For example, when the vacuum cleaner 1 without the contact portion 15 is simply leaned against the mounting portion 22, the main body 2 of the cleaner slides along either one of the mounting portions 22 to the left or right and falls down. Otherwise, the weight of the cleaner body 2 pushes the suction port 7 forward on the floor surface, and the cleaner body 2 slides downward between the installation parts 22 and falls down. Such an effect can be particularly conspicuous when the suction port body 7 is rotatably connected to the extension pipe 6 . On the other hand, in the first embodiment, the contact surfaces 19 of the contact portions 15 positioned on both sides of the axis A of the extension pipe 6 are placed in the corners by utilizing wall surfaces that intersect each other, such as the corners of a room or furniture. The vacuum cleaner 1 can be simplified without using a separate member or the like for hooking on a storage stand or a wall by suppressing the lateral or downward sliding of the vacuum cleaner body 2 side by abutting on the intersecting wall surface of the vacuum cleaner 1. It can be stored stably with a simple structure. Therefore, the vacuum cleaner 1 does not need to be stored in a fixed place such as a storage stand, and can be stored in any place having corners on both sides that intersect with each other.

In addition, since the contact portions 15 are located on both sides of the heavy object, the weight of the vacuum cleaner main body 2 of the vacuum cleaner 1 can be effectively supported by the contact portions 15 on both sides, and the electric cleaning in the housed state can be achieved. Machine 1 can be stabilized.

Furthermore, since the contact surface 19 of the contact portion 15 is formed in a flat shape, the contact surface 19 of the contact portion 15 and the installed portion 22 such as a wall surface are in contact with each other in a planar manner. The cleaner 1 can be stabilized.

Further, since the abutting portions 15 protrude from both sides of the cleaner body 2, compared with the case where the abutting portions 15 are provided on an inclined surface forming a part of the outer shell of the case body of the cleaner body 2, Therefore, the storage space for the parts stored inside the cleaner body 2 is not narrowed.

Furthermore, by providing the functional portions such as the connecting means 21a and the display means 21b on the surface portion 20 adjacent to the contact surface 19 of the contact portion 15 projecting on both sides, the position of the functional portion is easy for the user to understand, The arrangement space generated by the protrusion of the contact portion 15 can be effectively used.

Since the contact surface 19 of the contact portion 15 on one side and the contact surface 19 of the contact portion 15 on the other side intersect at a predetermined angle within a predetermined angle range from an acute angle to an obtuse angle, The contact surface 19 of the contact portion 15 can be effectively brought into contact with the intersecting installation portion 22, and the vacuum cleaner 1 can stand on its own without leaning against the installation portion 22. I can do it and can fix it more stably.

The abutting portion 15 may be retractable, or may be retracted to both sides by folding or the like.

The contact portion 15 may be biased in the advance direction by the biasing means, and may be held in the retracted state in the maximum retracted state. For example, a torsion spring, a coil spring, or the like may be used as the biasing means.

In this embodiment, part or all of the contact portion 15 can move back and forth. In the retracted state of the contact portion 15, the surface portion 20 is not exposed to the front portion of the vacuum cleaner 1. - 特許庁In this embodiment, the contact portion 15 is designed so that the surface portion 20 is stored inside the cleaner body 2 in the retracted state, as shown by the dashed line in FIG. 5(b).

By making the contact part 15 movable forward and backward on both sides of the electric vacuum cleaner 1, the contact part 15 is retracted when the contact part 15 is not used, such as cleaning, so that the contact part 15 can be used for vacuum cleaning. The use of the vacuum cleaner 1 can be prevented from becoming an obstacle, and the electric vacuum cleaner 1 can be stored stably by extending the contact part 15 when necessary.
