Abstract

PURPOSE:To clean efficiently not only a carpeted floor surface but a matting or wooden floor as well by a method wherein a nozzle is constituted in such a manner that an opening part is provided on the bottom surface, and at the same time, a suction part on the lower surface of which suction bodies with a vessel-shaped cross section, which have air suction holes, are arranged is detachably fastened to the opening part. CONSTITUTION:For a nozzle 10, an opening part 13 is provided on the bottom surface, and attaching parts 14 are stood at the edge of the opening part, and the nozzle 10 is connected to a suction pipe 11 at a connecting part 12. Also, a suction part 16 is constituted in such a manner that a plurality of suction bodies 20 are arranged on a flat plate 17, on the side parts of which flanges 18 are stood, and a protuberance 19 which is fastened to a recessed part 15 on the attaching part 14 is formed on the flange 18. The cross section of the suction body 20 is formed into a vessel shape, and one or a plurality of air suction holes 21 are provided on the suction body 20. The suction part 16 is detachable to the bottom surface of the nozzle 10 by fastening or removing the protuberance to/from the recessed part of the attaching part. When a carpeted floor surface is cleaned, the suction part 16 is fitted to the attaching part 14, and when a matting or wooden floor 22 is cleaned, the suction part 16 is removed, and the opening part 13 is confronted to the floor surface.

Particularly recently, carpets with particularly long piles have become popular in households, but it is extremely difficult to collect the dirt that accumulates at the base of the long piles using a regular vacuum cleaner nozzle. Nozzles have also been developed. Figure 4 is a cross-sectional view of a vacuum cleaner developed for cleaning long-pile carpets, Figure 5 is a partially enlarged view, and Figure 6 is an enlarged view of a protrusion. 3 is a nozzle, 3 is a protrusion with holes 3a, 4 is a rotating brush, 5 is a dust collection bag,
6 is the air flow, 7 is the carpet, and 7a is its pile. This vacuum cleaner has a nozzle 2 with a large number of protrusions 3 arranged orthogonally to the moving direction of the nozzle. When cleaning a carpet with a long pile 7a, the tips of the protrusions 3 are
The purpose is to reach the root of the bristles 7a and collect dirt and the like by suctioning them through the hole 3a.

２を押して移動させながらの掃除は困難である。[Problem to be Solved by the Invention] However, when cleaning is attempted using a nozzle equipped with the protrusion described above, the long hair of the carpet comes into contact with the protrusion 3 disposed on the nozzle 2, causing the nozzle 2 to move. This creates a large resistance to the movement of the nozzle 2, making it very difficult to move the nozzle 2, and it is practically difficult to clean while pushing and moving the nozzle 2.

こととなる。Furthermore, even if the nozzle 2 can be moved on the carpet floor surface, the nozzle cannot be used to suck and collect dirt and hair adhering to the vicinity of the base of the pile 7a of the carpet 7, that is, the deep part of the pile 7a. Although it is effective, it is not necessarily effective for cleaning between tatami mats and boards. In other words, in the case of a tatami mat or between a board, it is better to inhale air from an air inlet with a larger suction area than to inhale air from a small diameter hole like the air suction hole 4 of the suction body mentioned above, because there is less resistance to the air intake. This is because the amount increases and cleaning efficiency is high. Therefore, even if you use the above nozzle on a carpeted floor, it is normal to replace it with a dedicated nozzle on a tatami floor or between boards, and when cleaning floors with different specifications, it is time consuming to replace the nozzle. That's what it takes.

Can be easily collected by suction.

Note that the nozzle 10 is connected to the suction pipe 11 at a connecting portion 12. The suction part 16 is formed by arranging a plurality of suction bodies 20 on a flat plate 17 having a flange 18 upright on the side, and the flange 18 is formed with a convex part 19 that engages with the concave part 15 of the mounting part 14. ing. The suction body 20 has a boat-shaped cross section, and is provided with one or more air suction holes 21 . The nozzle 10 of the vacuum cleaner according to the present invention is configured as described above, and the suction part 16 is attached to and detached from the bottom surface of the nozzle 10 by engaging or removing the convex part of the suction part 16 with the concave part of the nozzle mounting part. It is free.

。When cleaning a carpet floor using the vacuum cleaner nozzle 10 according to the present invention, as shown in FIG. If you move it, the dirt on the floor will be removed from the suction part 1.
It is sucked together with air from the air suction hole 21 of the suction body 20 of No. 6. Since both ends of the suction body 20 are tapered in the direction of movement, the suction body 20 receives almost no resistance from the piles 7a of the carpet when the nozzle is moved, and can be easily moved.
