Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor suction tool used in a vacuum cleaner.
[0002]
[Prior art]
Conventionally, floor suction tools used for vacuum cleaners have wheels on the bottom surface considering mobility in the front-rear direction, but when cleaning the flooring, sand etc. has fallen on the flooring In such a case, sand or the like is caught between the wheel and the flooring, and particularly when the floor suction tool is moved in the lateral direction, there is a problem that the flooring is damaged by the sand or the like.
In order to solve this drawback, as disclosed in Japanese Utility Model Publication No. 61-77936 (A47L 9/02), it is conceivable to attach a felt or a flocked member to the bottom surface of the suction tool body.
[0003]
However, felt and flocking members are only stuck to the suction tool body as the brushed cloth gets caught and the mobility of the suction tool body becomes worse when cleaning carpets with relatively high frictional resistance. Therefore, there is a problem that the felt and the flocked member are easily peeled off due to the back-and-forth movement of the suction tool body during cleaning.

[0015]
Reference numeral 11 denotes a brush body serving as a suction keeper disposed at the rear part of the suction port 8 over substantially the entire width of the suction port 8 to prevent air leakage from the rear of the suction port 8 and prevent a decrease in suction force. It is supposed to be.
[0016]
Reference numeral 12 denotes an auxiliary wheel disposed at the rear edge of the suction port 8 that supports the suction tool body 4 and improves the mobility of the suction tool body 4.
[0017]
13 is a raised cloth pasted from the bottom surface of the suction tool body 4 to the front surface on both sides of the suction port 8, and when the lower surface of the raised cloth 13 is placed on the floor surface of the suction tool body 4, It is arrange | positioned in the height which contacts a floor surface.
[0018]
14 is a brush body arranged at the front end of both sides of the suction tool body 4 corresponding to the raised cloth 13, and when the suction tool body 4 is placed on the floor and advanced, the brush body 14 The suction tool body 4 is bent toward the rear side, that is, the raised cloth 13 side, and the curved surface of the bent brush body 14 makes the suction tool body 4 easy to slide on the floor, improving the mobility of the suction tool body 4. When the suction tool main body 4 is moved in the left-right direction, the brush body 14 scrapes off dust on the wall.
[0019]
The brush body 14 is configured such that the lower end of the brush body 14 is located below the lower surface of the raised cloth 13 in a state where the suction tool body 4 is lifted, and the brush body 14 is moved forward on the floor surface. When the body 14 bends, the brush body 14 can reliably cover the front end portion of the raised cloth 13, reduce the frictional resistance of the raised cloth 13, and improve the mobility of the suction tool body 4.
[0020]
Since the brush body 14 is formed in a position and length that overlaps the raised cloth 13 in a state where the brush body 14 is bent, the brush body 14 is particularly useful when cleaning a surface to be cleaned having a high frictional resistance such as a carpet. The body 14 can reliably cover the front end portion of the raised cloth 13, reduce the frictional resistance of the raised cloth 13, and improve the mobility of the suction tool body 4.
[0021]
Further, the brush body 14 is arranged wider than the width of the raised cloth 13, and when the brush body 14 is bent, it covers the front end portion of the raised cloth 13 over the entire width of the raised cloth 13 and has a large frictional resistance. Even when the carpet is cleaned, the frictional resistance of the raised cloth 13 can be reduced and the mobility of the suction tool body 4 can be improved more reliably.
[0022]
According to the above configuration, by arranging a brushed cloth on the front bottom surface of the suction tool main body 4, even when sand or the like has fallen on the flooring when cleaning the flooring, in order to capture the sand in the raised cloth 13, In particular, when the floor suction tool is moved laterally, it is possible to prevent the flooring from being damaged by sand or the like, and by arranging the brush body 14 corresponding to the raised cloth 13 at the front end of the suction tool body, in particular, When the suction tool body 4 is advanced with a cleaning surface having a high frictional resistance such as a carpet, the brush body 14 is bent to cover the front end portion of the raised cloth 13, and the suction tool body 4 is brought to the floor surface by the curved surface of the bent brush body 13. It is possible to improve the mobility of the suction tool body 4 by making it easy to slide on.
[0023]
Further, the brush body 14 is arranged on the front side of the raised cloth 13 so that the brush body 14 covers the front end portion of the raised cloth 13 when the suction tool body 4 is advanced on the floor surface. Can be prevented from coming into contact with the floor surface, and the raised cloth 13 can be prevented from peeling off while the suction tool body 4 is repeatedly moved back and forth.
[0024]
Since the lower end of the brush body 14 is formed to be longer than the lower surface of the raised cloth 13, the brush body is moved when the suction body 4 is advanced on the floor and the brush body 14 is bent toward the raised cloth 13 side. Since 14 reliably covers the front end portion of the raised cloth 13, the curved surface of the bent brush body 14 makes the suction tool body 4 slip easily on the floor surface, and the mobility of the suction tool body 4 can be improved.
[0025]
Further, since the brush body 14 is arranged wider than the width of the raised cloth 13, the brush body 14 is bent to cover the front end portion of the raised cloth 13 over the entire width, thereby cleaning the carpet having a large frictional resistance. Even at that time, the frictional resistance of the raised cloth 13 can be reduced and the mobility of the suction tool body 4 can be improved more reliably.
[0026]
If the brush body 14 is made of nylon, fluorine fiber or the like having low friction resistance, the mobility can be further improved.
[0027]
