JPH0751194A - Suction tool for floor for vacuum cleaner - Google Patents

Abstract

PURPOSE:To sweep fine dust and to improve dust collection performance and a cleaning effect by forming a groove for collapse between a recessed groove and a base part inserted to and fitted in a groove formed in the circumferential longitudinal direction of a rotator. CONSTITUTION:One terminal of a cleaning member 46 formed from synthetic fiber and natural fiber, etc., is inserted to the recessed groove, and the tip of the cleaning member is arranged so as to protrude over the tip of a projecting belt 39, then, they are integrated. When an agitator is rotated on a floor in a counter-clockwise direction, the cleaning member 46 is displaced in a clockwise direction when it is abutted with a plane to be cleaned, and it is moved relatively so as to sweep the floor. Also, when a carpet is rotated in the clockwise direction, the projecting belt 39 is displaced when it comes in contact with the plane to be cleaned, which forms it in shape to be set along the plane to be cleaned. Dust is squeezed by a large number of projections 42, then, it can be separated. Furthermore, the inclination sparseness of the agitator can be secured by forming the groove 44 at a foot part to which the highest torque is applied at the projecting belt 39, which generates higher deflection. Also, when the belt comes in contact with the carpet, burden on a motor can be reduced, which improves durability.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction tool for an electric vacuum cleaner having a rotating brush body rotated by an electric motor.

[0002]

2. Description of the Related Art Conventionally, in this type of floor suction device for an electric vacuum cleaner, an agitator provided with a ridge band generally has a structure as disclosed in, for example, Japanese Unexamined Patent Publication No. 1-151743. . The configuration will be described below with reference to the drawings. As shown in FIG. 8, an agitator 2 and a driving source 3 for the agitator 2 are provided in the floor suction tool body 1, and the agitator 2 is made of a flexible material in the longitudinal direction of the circumferential surface of the rotor 4, It is configured by providing a ridge strip 5 having a large number of projections on one surface, and a switch for operating the drive source 3 is provided at the proximal portion (not shown) of the hose.

[0003]

However, in the construction of the floor suction tool of the conventional vacuum cleaner, the rotary brush is used for cleaning the carpet, and cleans the tatami mat and the wooden floor. At that time, the dust was removed by the suction force of the vacuum cleaner body, but the dust removal between the orchids on the tatami mat and the ejection of fine dust on the floor were insufficient.
Further, even if powder or the like is accidentally spilled on the wooden floor, there is a problem that the suction force alone cannot sufficiently remove the powder. The present invention solves this problem, and aims to improve the dust collection performance and the brushing effect by ejecting fine dust on the floor surface or tatami mat.

[0004]

In order to achieve the above object, the first means of the present invention is to install an agitator and a drive source for the agitator in the main body of the suction tool, wherein the agitator has a rotor and The ridge band is inserted and held in a spiral shape in the longitudinal direction of the peripheral surface of the rotor, and further comprises a ridge band having a large number of protrusions on the rotation direction side, and the ridge band forms a main body portion with a soft material and has the protrusion. A concave groove is provided on the opposite surface, and a polishing member made of a compression material such as synthetic fiber and natural fiber is arranged in the concave groove and integrated, and inserted from the concave groove into a groove formed in the longitudinal direction of the circumferential surface of the rotor. It is configured by providing a groove for sagging between the fitting base and the base.

A second means is to form a positioning rib for regulating the arrangement of the polishing member made of a compression material such as synthetic fiber or natural fiber at the end portion on the opposite surface side having the projection.

[0006]

In the first means of the present invention, the ridge band of the agitator has a main body made of a soft material, and a groove is provided on the opposite surface having the protrusion, and the groove is combined with the groove. A polishing member composed of a compression material such as fiber or natural fiber is arranged and integrated, and a groove for flapping is provided between the concave groove and a base portion which is inserted and fitted into a groove formed in the longitudinal direction of the circumferential surface of the rotor. Since it is configured, when cleaning the wooden floor, the polishing member protruding from the tip of the ridge will come into contact, but since the polishing member is a soft cloth, the contact area with the surface to be cleaned can be wide. Dust between orchids on the tatami mat, which is well-known on the surface, is removed, and the ejection of fine dust on the floor is improved, and it is possible to prevent entanglement of hair and thread waste compared to a cut pile spun cloth made of fine fibers. . In addition, when cleaning the carpet, it is possible to scrape out dust efficiently due to the nature of the flexible material, causing the ridges to be bent and conforming well to the surface, and squeezing action. In addition, since a groove is formed in the root portion where the rotation force of the agitator is most applied to the ridge, the load on the motor is reduced at the time of contact with the carpet, and the durability is improved.

In the second means, since the positioning ribs are formed at both ends of the ridge strip, it is possible to easily position the sewing operation of the polishing member made of the compressed material such as the synthetic fiber and the natural fiber, and the quality is improved. The sewing end can be reinforced as well as improved.
