Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner suction tool.

[0002]

2. Description of the Related Art Conventionally, this kind of suction tool has a structure as shown in a perspective view of FIG. 4 (for example, JP-A-1-114714), and has a lower portion having a suction port 1 for sucking dust and the like. A bank-shaped mounting seat 3 is formed on the outer peripheral portion of the suction tool 2, and a raised cloth 4 made of a cut pile spun cloth is provided on the mounting seat 3.

[0003]

However, in such a structure, since the raising cloth 4 is integrally provided to the lower suction tool 2, the raising cloth 4 having an extremely fine and high density has a space between the straw mats of the tatami mat. In order to sufficiently bring out the dust-exhausting effect and the effect of wiping off the fine dust on the floor surface, there was a drawback in that the back-and-forth movement of the suction tool had to be reciprocated many times at the same location.

Further, when cleaning the carpet, there is a drawback in that the carpet and the raised cloth 4 rub strongly and become heavy, resulting in poor operability.

The present invention solves the above-mentioned problems, and can exhibit the effect of wiping out and wiping the raised cloth with a small number of back and forth movements of the suction tool, and even on the carpet, the cleaning work can be performed with a light operating force. It is an object of the present invention to provide a suction tool for a vacuum cleaner that can perform the above.

[0006]

The present invention comprises a suction tool body having a suction port, a disc rotatably provided on the lower surface of the suction tool body, and a cut pile-shaped spun cloth provided on the lower surface of the disc. A raised fabric, the disk is configured to be inclined with respect to the surface to be cleaned, the outer peripheral portion of the disk and the surface to be cleaned is wide in the vicinity of the suction port near the left and right ends of the suction tool body. It is configured so as to be inclined in the narrowing direction.

[0007]

According to the present invention, since the rotatable disk having the raising cloth on the lower surface is provided in a state of being inclined with respect to the surface to be cleaned, when the cleaning work is performed by the suction tool, the disk is rotated. If the raised cloth at the position farthest from the lower surface of the suction tool on the outer peripheral portion comes into contact with the surface to be cleaned, and further by moving the suction tool forward, the contact point with the surface to be cleaned serves as the base point and the center of the disk acts forward. At the same time, a rotational force is applied to the disk, and the base point sequentially moves the disk end portion, and the disk also rotates as the suction tool moves forward.

At this time, the raising cloth located symmetrically with respect to the center of rotation of the disk rotates in the same direction as the advancing direction of the suction tool, and the raising cloth cleans the surface to be cleaned with a so-called broom. It works like this. Therefore, compared with a conventional suction tool with a raised cloth integrally attached,
The dust ejecting effect and the wiping effect can be sufficiently exerted with a small number of front and rear operations of the suction tool. Further, since the frictional force between the disk and the surface to be cleaned is reduced due to the rotation of the disk, the operation resistance associated with the front and rear operation of the suction tool is reduced, and the cleaning operation can be performed with a lighter operation.

Further, the disc and the brushed cloth are provided in the vicinity of the left and right sides of the suction port, and are inclined in a direction in which the distance between the outer peripheral portion of the disc and the surface to be cleaned is wide near the suction port and narrow near the left and right ends of the suction tool body. Therefore, the napped cloth sweeps out against the surface to be cleaned, wipes and polishes near the suction opening, and the dust swept up by the napped cloth is quickly and surely sucked from the suction opening. It is something that can be cleaned well.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of a suction tool according to an embodiment of the present invention as seen from the front, FIG. 2 is a side sectional view of the suction tool of FIG. 1, and FIG. 3 is a bottom view of the suction tool of FIG. FIG. Figure 1
3 to FIG. 3, 10 is a suction tool body, and upper suction tool 11,
A suction chamber having a lower opening formed in the front of the suction tool body 10 by connecting the lower suction section 12 to each other.
14 are formed. As shown in FIG. 2, the center of the suction chamber 14 is located behind the suction tool body 10 and includes an upper suction tool 11 and a lower suction tool.
The communication pipe 15 sandwiched between the 12 and the connection pipe 16 rotatably coupled to the communication pipe 15, and the connection pipe 16,
An extension pipe communicating with a suction side of the electric vacuum cleaner via a hose is detachably connected.

A bearing holder 17 is formed in the lower suction tool 12, and a bearing 18 is provided in the bearing holder 17.
Thus, the rotary shaft 19 is rotatably provided. A disc 20 is press-fitted and fixed to the tip end portion of the rotary shaft 19, and a raised fabric 21 made of a cut pile spun fabric is adhesively fixed to the lower face of the disc 20. Reference numeral 22 is a retaining ring that prevents the rotating shaft 19 from coming off the bearing 18. The bearing holder 17
Holds the bearing 18 so that the disk 20 is inclined with respect to the surface to be cleaned.

Next, the operation and action of this embodiment will be described. When the suction tool body 10 is placed on the surface to be cleaned, the disk
Since 20 is inclined with respect to the surface to be cleaned,
The raised cloth 21 bends due to the strong contact force at the portion A where the distance to the surface to be cleaned is narrow, and only the tip portion of the raised fabric 21 at the portion B where the distance to the surface to be cleaned is wide. Contact with.

When the suction tool body 10 is moved forward (in the direction of the arrow A in FIG. 2) in this state, the raised cloth of the A section is rubbed between the raised cloth 21 of the A section and the surface to be cleaned. 21 becomes a stop state for a moment and acts as a base point, so that the center part of the disk 20 acts forward and at the same time imparts a rotational force to the disk 20, and the base point sequentially moves the ends of the disk 20. As the suction tool body 10 moves forward, the disk 20 also rotates. At this time, the nap cloth 21 located symmetrically with respect to the rotation center of the disk 20 rotates in the same direction as the advancing direction of the suction tool body 10, and the nap cloth 21 with respect to the surface to be cleaned.
A so-called broom works like cleaning. The same effect is obtained when the suction tool body 10 is moved in the rearward direction (direction of arrow B in FIG. 2).

Therefore, as compared with the conventional suction tool in which a raised cloth is integrally attached, the dust ejecting effect and the wiping effect can be sufficiently exerted with a small number of forward and backward operations of the suction tool main body 10. .. Further, the suction tool body 10 is in contact with the surface to be cleaned via the rotatable disk 20, and the disk 20 rotates in response to the front-back movement of the suction tool body 10, and the suction tool body 10 and the surface to be cleaned are In order to reduce the frictional resistance generated between them, the cleaning work can be performed with a light operating force.

Further, the disk 20 is provided in the vicinity of the left and right sides of the suction port 13, and the inclination direction of the disk 20 is wide in the vicinity of the suction port 13 in the vicinity of the suction port 13 and in the vicinity of the left and right ends of the suction tool body 10. Since it is configured to be narrow, when cleaning work is performed on the suction tool body 10, a raised cloth 21 is provided near the left and right sides of the suction port 13.
Performs a high-speed sweeping operation against the cleaning surface
The dust swept out at 21 is immediately sucked through the suction port 13, and the cleaning work can be performed more efficiently with respect to the reciprocating movement of the suction tool body 10.
