According to the second aspect of the present invention, the attachment portion of the attachment is a concave portion having a substantially external shape of the attachment, and the holding area during attachment can be easily increased, and the attachment direction to the user, etc. In addition, the guide effect by visibility can be dramatically improved.
[0008]
The invention according to claim 3 of the present invention is such that another concave portion is continuously formed in the concave portion having a substantially appearance shape of the attachment, so that grip ease associated with attachment / detachment of the attachment is improved and usability is improved. It will be connected with.
[0009]
In the invention according to claim 4 of the present invention, the attachment mounting portion is formed so that the attachment is inclined with respect to the surface to be cleaned when the attachment is mounted. As a design configuration, the projection of the attachment easily mounted on the exhaust cover is formed. The part can be formed, and the ease of grip when attaching and detaching is improved, leading to improved usability.

【Example】
Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0011]
Reference numeral 20 denotes a vacuum cleaner body which includes a suction tool 21 for sucking dust downward and incorporates an electric blower (not shown) for generating suction air. Is installed. The exhaust cover 23 is configured to rectify exhaust air that is an outlet of exhaust air emitted from the electric blower of the cleaner body 20 and is discharged from an outlet 27 provided in the cleaner body 20. A recess 25 is formed as an attachment portion for holding and attaching the attachment 24 attached to the cleaner body 20 in the same manner. At least a part of the attachment 24 is located below the exhaust port 26, and when the attachment 24 is mounted, the outer shape of the attachment 26 protrudes from the outer shape of the exhaust port 26. Further, the concave portion 25 has a concave shape that approximates the external shape of the attachment 24, and the upper and lower ends thereof engage with the receiving portions 28 of the concave portions provided in the attachment 24 to be attached. A projection fitting portion 29 and a claw fitting portion 31 that is engaged with the pipe inner surface 30 at the other end of the attachment 24 are configured. Further, also in the attachment form of the attachment 24 to the attachment part 25, the hollow pipe 32 side formed so that the attachment 24 is connected to the suction part of the cleaner main body 20 is connected to the cleaner main body that is grounded and attached to the surface to be cleaned. Similarly, the vacuum cleaner main body 20 is mounted and mounted so as to face upward, and at the same time, it is configured to achieve an arbitrary inclination.
[0012]
Further, in the engagement configuration for the purpose of holding at the time of mounting, the arrangement of the receiving portion 28 of the concave portion, the fitting portion 29 of the convex portion, and the claw fitting portion 31 is configured as the axis of the hollow pipe 32 of the attachment 24 The position is shifted in one of the left and right directions from the center line 33.
