Further, on the right and left sides of the upper surface of the cleaning wiping sheet 9, a pair of temporary fixing means 45 for temporarily fixing the cleaning wiping sheet 35 for cleaning the floor surface F as the cleaning surface are provided. In the present embodiment, the temporary fixing means The 44 is a hook-like surface of a surface fastener, and has a plurality of protrusions whose front ends are bent in a hook shape.

Next, the action of this embodiment will be described. First, the case where the floor surface F is wiped and cleaned using the above-described cleaning wipe sheet 35 will be described in detail. When the cleaning floor surface F is wiped by using the cleaning wiping sheet 35, the user removes the cleaning wiping sheet 9 from the nozzle 8. At this time, the cleaning wiping sheet 9 is magnetically connected to the steel plate 28 by the magnet member 40, and is attached to the nozzle 8 by the magnet member 40. Therefore, the force equal to or higher than the adsorption force due to the magnetism of the permanent magnet 40A faces downward. The stretching is thereby easily removed by the aforementioned nozzle 8. Next, the cleaning wiping sheet 9 is placed on the cleaning wiping sheet 35, and the front and rear portions of the cleaning wiping sheet 35 are respectively bent and superposed on the cleaning wiping sheet 9. Further, the left and right front portions and the rear portions of the cleaning wiping sheet 35 are respectively pushed to the temporary fixing means 45. As is generally known, the cleaning wipe sheet 35 is formed by a nonwoven fabric that bundles a plurality of fine fibers. Therefore, the fine fibers of the cleaning wiping sheet 35 are caught by the hook-shaped projections of the temporary fixing means 45. Thereby, the cleaning wipe sheet 35 is temporarily fixed. However, the hook-shaped projection of the temporary fixing means 45 cannot hold the cleaning wiping sheet 35 with the strength that can be maintained to that extent.

Then, the convex portion 39 is inserted into the concave portion 27, and the magnet member 40 of the joint portion 42 is magnetically connected to the steel plate 28 of the joint portion 29, whereby the cleaning wiper 9 for temporarily cleaning the cleaning wipe sheet 35 is again fixed. Installed in the aforementioned nozzle 8. At this time, the first engaging convex portion 43 of the cleaning wiper 9 is inserted into the first opening portion 32 of the nozzle 8. another On the other hand, the second engaging convex portion 44 of the cleaning wiper 9 is inserted into the second opening portion 33 of the nozzle 8. As described above, the first engaging convex portion 43 and the second engaging convex portion 44 are inserted into the first opening portion 32 and the second opening portion 33, so that the cleaning wiper 9 is surely opposed to the nozzle 8 Positioning. Therefore, the cleaning wiping sheet 9 suppresses the horizontal instability with respect to the nozzle 8. Next, the cleaning wiping sheet 35 is sandwiched between the concave portion 27 and the convex portion 39, between the first opening portion 32 and the first fastening convex portion 43, and the second opening portion 33 and the second portion Between the engaging convex portions 44 and between the magnetic conductive portion 40B and the steel plate 28 described above. As described above, the cleaning wipe sheet 35 is sandwiched between the nozzle 8 and the cleaning wiper 9, whereby the cleaning wipe sheet 35 is attached to the nozzle device 3. The cleaning wiper 9 is attached to the nozzle 8 so as to be substantially parallel to the suction port 22 at the rear of the suction port 22. Therefore, there is no case where the cleaning wiper 9 closes the suction port 22.

Here, as described above, the soft member 37 is made of a material having rubber elasticity and being hard to slide, and a plurality of protrusions 38 are provided on the entire lower surface of the soft member 37. Therefore, when the cleaning wiping sheet 35 is pressed against the floor surface F, the soft member 37 is elastically deformed, and the floor surface F can be abutted with appropriate strength. Further, by the plurality of projections 38 provided on the entire lower surface of the soft member 37, the cleaning wiping sheet 35 is prevented from moving relative to the cleaning wiping sheet 9 in the horizontal direction. Therefore, even if the wiping cleaning is continued, the cleaning wiping sheet 35 is prevented from being stretched in the horizontal direction and slackened.

As shown above, the aforementioned tube to which the above-described cleaning wiper 9 is attached The nozzle device 3 is attached to the aforementioned cleaner body 2. In this state, the user holds the first handle 10 or the second handle 11 so that the cleaning wipe sheet 35 abuts against the floor surface F and moves along the floor surface F. At this time, the dust on the floor surface F is removed by the cleaning wiping sheet 35, and is removed by the floor surface F. As described above, the floor surface F is wiped and cleaned by the above-described cleaning wipe sheet 35. However, as described above, the suction port 22 is not blocked by the cleaning wiper 9. Therefore, the electric vacuum cleaner 1 in which the nozzle device 3 is mounted can simultaneously suck the dust on the floor surface F by the suction port 22 while wiping the floor surface F by the cleaning wiping sheet 35.

The concave portion 27 constituting the joint portion 29 of the nozzle 8 is closed by the convex portion 39 constituting the joint portion 42 of the cleaning wiping sheet 9 and the cleaning wipe sheet 35. Further, the steel plate 28 magnetically connected to the magnet member 40 is located in the inner portion of the concave portion 27 constituting the joint portion 29 of the nozzle 8, that is, the upper portion of the concave portion 27. Therefore, even if the steel plate 28 is magnetically connected to the magnet member 40, the steel plate 28 can be magnetically connected to a staple or a crepe pin on the floor surface F, and the steel plate 28 cannot be reached. Further, it is assumed that there is a gap between the concave portion 27 of the nozzle 8 and the convex portion 39 of the cleaning wiping sheet 9 or the cleaning wiping sheet 35, and is also formed in a state in which a staple or a stapling needle can be magnetically connected. Since the steel plate 28 is located far from the floor surface F, the staples, the crease pins, and the like can be prevented from being magnetically attached to the steel plate 28. Further, it is assumed that a staple or a stapling needle or the like is magnetically attached to the steel plate 28, and if the cleaning wiper 9 is detached from the nozzle 8, the steel plate 28 cannot continue to magnetically engage a staple or a crepe. Further, it is assumed that the steel sheet 28 is magnetized by the permanent magnet 40A, and the steel sheet 28 is Since the magnetic force is also extremely weak, the staple or the stylus which is magnetically attached to the steel plate 28 can be easily removed. Among them, compared with the steel plate 28 described above, it is highly probable that a staple or a stapling needle is magnetically coupled to the magnetic conductive portion 40B of the magnet member 40. However, by covering the magnetic conductive portion 40B by the cleaning wiping sheet 35, the cleaning wiping sheet 35 can be removed, and the staple, the crease or the like can be easily removed by the magnetic conductive portion 40B. Further, even if the staple or the stapling needle is directly magnetically coupled to the aforementioned magnetic conductive portion 40B, these can be easily recognized and removed. As described above, the staple or the stapling needle or the like is not magnetically coupled to the joint portion 29 of the nozzle 8, and even if the staple or the back stitch is magnetically coupled to the joint portion 42 of the cleaning wiper 9, it is easy. Remove. Therefore, when the cleaning wiper 9 is attached to the nozzle 8, the cleaning wiper 9 is prevented from being tilted with respect to the nozzle 8 due to a staple or a stapling needle, or the magnetic connection is insufficient, and the cleaning is performed. The case where the board 9 falls off. Therefore, the cleaning blade 9 can be normally attached to the nozzle 8, and the wiping cleaning is performed by the cleaning wiping sheet 35 as it is.

Next, the case where only the suction cleaning on the floor surface F is performed will be described in detail. When the vacuum cleaner 1 is only used for suction cleaning of the floor surface F, there are two methods for the user. In the first method, as shown in FIGS. 7 to 9, the cleaning wiper 9 is not attached to the nozzle 8, and the vacuum cleaner 1 is used. In this case, the nozzle 8 is provided with the steel plate 28 that is not magnetic. Therefore, even if the nozzle 8 is attached to the nozzle 8 and the floor surface F is suctioned and cleaned, the nozzle or the back stitch can be used. Etc. will not be magnetically connected to the aforementioned nozzle 8. However, since the magnet member 40 and the steel plate 28 are in contact with each other for a long time, the steel plate 28 may be weakly magnetized. However, the steel plate 28 The magnetic force is only extremely weak. Further, as described above, the steel plate 28 is located at a position sufficiently higher than the floor surface F. Therefore, the staple or the stylus on the floor surface F is not magnetically connected to the steel plate 8 of the nozzle 8.

In the second method, as shown in FIGS. 1 to 5, the above-described electric vacuum cleaner 1 is used only by attaching the cleaning wiper 9 to the nozzle 8. At this time, as shown in FIG. 5, the lower end of the cleaning wiper 9 is located at a plane connecting the grounding point of the front wheel 23 as the grounding point of the front floor surface and the grounding point of the rear wheel 24 as the grounding point of the rear floor surface. , that is, the position above the floor surface F of the surface to be cleaned. That is, even if the cleaning wiper 9 is attached to the nozzle 8 and the vacuum cleaner 1 is used, the cleaning wiper 9 does not come into contact with the floor surface F. Therefore, even if the vacuum cleaner 1 is used while the cleaning blade 9 is attached to the nozzle 8, the dust can be sucked by the suction port 22. Therefore, the user does not need to remove the cleaning wiper 9 by the nozzle 8 to use the vacuum cleaner 1. Therefore, it is possible to keep the cleaning wiper 9 fixed to the nozzle 8 at all times, and therefore it is not necessary to separately store the cleaning wiper 9. Therefore, the fear of losing the aforementioned cleaning wiper 9 can be reduced.
