Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a suction tool of this type has a structure as shown in a perspective view of FIG. 4 (for example, Japanese Patent Laid-Open No. 114714/1989) and has 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 lower suction tool 2 having the above, and the mounting seat 3 is provided with a raised cloth 4 made of a cut pile spun cloth.

[0003]

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

Further, when cleaning the carpet, there is a problem 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 exert the extruding effect and the wiping effect even if the suction tool is moved a few times, and the electric cleaning can be performed on the carpet with a light operation force. An object is to provide a suction tool for machines.

[0006]

According to the present invention, there is provided a suction tool body having a suction port, a rotating body disposed below the suction tool body and rotatable to the left and right of the suction port, and a lower surface of the rotating body. And a rotary shaft that rotatably attaches the rotating body to the suction tool body, the rotation shaft being inclined from the suction port side toward the left and right sides of the suction tool body, The lower surface of the rotating body is inclined in different directions with respect to the surface to be cleaned.

Further, the rotating shaft is inclined so as to approach the suction port toward the lower end thereof, and the gap between the outer peripheral portion of the rotating body and the surface to be cleaned is wide near the suction port and narrow on the left and right sides of the suction tool body. It is a structure tilted in the direction.

[0008]

According to the present invention, since the rotatable rotary member having the wiping member on the lower surface is provided in a state of being inclined with respect to the surface to be cleaned, when cleaning work is performed with the suction tool, The wiping member at the position farthest from the lower surface of the suction tool on the outer peripheral portion of the rotating body comes into contact with the surface to be cleaned, and by further moving the suction tool forward, the contact point with the surface to be cleaned serves as a base point and the rotary shaft portion of the rotating body Acts on the rotating body at the same time as it acts forward, the base point sequentially moves along the outer peripheral end of the rotating body, and the rotating body also rotates with the forward movement of the suction tool. .

At this time, since the wiping member provided on the lower surface of the rotating body also rotates, the wiping member acts on the surface to be cleaned as if cleaning it with a so-called broom. Therefore, as compared with the conventional suction tool in which the wiping member 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. Moreover, since the frictional force with the surface to be cleaned is reduced by the rotation of the rotating body, the operation resistance associated with the front-back operation of the suction tool is reduced, and the cleaning operation can be performed with a lighter operation.

Further, since the rotary body is arranged on the left and right sides of the suction port, the dust swept out by the rotation of the rotary body is quickly and surely sucked from the suction port, and the cleaning work can be carried out more efficiently.

Further, the rotary shaft is inclined from the suction port side toward the left and right sides of the suction tool body, and the lower surfaces of the left and right rotating bodies are inclined in different directions with respect to the surface to be cleaned, for example, the suction port is a boundary. If the left and right rotating bodies are tilted like a letter C, the base points of the left and right rotating bodies are the left and right outer end sides, and the rotating directions of the left and right rotating bodies on the suction port side of the suction tool body are the same. Becomes Therefore, the sweeping direction of the rotating body in the vicinity of the suction port is the same, and the dust swept out by the left and right rotating bodies smoothly flows into the suction port. When the left and right rotating bodies are tilted in a V shape, the rotation direction of the left and right rotating bodies near the suction port is forward when the suction tool body is moved forward, and the suction tool body is moved backward. When moved, the rotation direction near the suction ports of the left and right rotating bodies is rearward. Therefore, the moving direction of the main body of the suction tool and the rotating direction of the left and right rotating bodies near the suction ports are the same, and the swept dust can be efficiently sent to the suction ports.

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
In FIG. 3 to FIG. 3, reference numeral 10 designates a suction tool body and an upper suction tool 1
1. It is configured by connecting the lower suction tool 12,
A suction chamber 14 having a lower opening as a suction port is formed inside the front of the suction tool body 10. The center of the suction chamber 14 is
As shown in FIG. 2, the upper suction tool 1 is provided behind the suction tool body 10.
1. A communication pipe 15 sandwiched between the lower suction tool 12 and a connection pipe 16 rotatably connected to the communication pipe 15. The connection pipe 16 has a hose on the suction side of the vacuum cleaner. An extension pipe that communicates with each other is detachably connected.

A bearing holding portion 17 is provided in the lower suction tool 12.
The rotary shaft 19 is rotatably provided by the bearing 18 provided in the bearing holder 17. A disk 20 as a rotating body is provided at the tip of the rotating shaft 19.
Is press-fitted and fixed, and a raised fabric 21 made of a cut pile-shaped spun cloth as a wiping member is adhesively fixed to the lower surface of the disk 20. A retaining ring 22 prevents the rotary 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 20 is provided so as to be inclined with respect to the surface to be cleaned, so that the contact force is strong at the portion A where the distance from the surface to be cleaned is narrow. The raised cloth 21 is bent and the space between the surface to be cleaned is wide B
In the section, only the tip of the raised fabric 21 contacts the surface to be cleaned.

In this state, the suction tool body 10 is moved forward (see FIG. 2).
(2) in the direction of the arrow A), due to the frictional resistance generated between the raised cloth 21 of the A section and the surface to be cleaned, the raised cloth 2 of the A section
1 becomes a stop state for a moment and serves as a base point. Therefore, the central portion of the disk 20 acts forward, and at the same time, a rotational force is applied to the disk 20. Then, the base point sequentially moves the end portion of the disk 20, and the disk 20 also rotates as the suction tool body 10 moves forward. Disk 2 at this time
The napped cloth 21 at the symmetrical position with respect to the rotation center of 0 rotates in the same direction as the advancing direction of the suction tool body 10, and the napped cloth 21 rotates in the same direction as the surface to be cleaned. Works as if cleaning the surface to be cleaned with a so-called broom. Also, behind the suction tool body 10 (see FIG.
The same effect is obtained even when it is moved in the direction of arrow B).

Therefore, as compared with the conventional suction tool in which a raised fabric 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 to cause the suction tool body 10 and the surface to be cleaned to move. In order to reduce the frictional resistance generated between them, the cleaning work can be performed with a light operating force.

The disc 20 is provided in the vicinity of the left and right sides of the suction port 13, and the inclination direction of the disc 20 is wide in the vicinity of the suction port 13 with respect to the surface to be cleaned.
Since it is configured to become narrow near the left and right ends, when cleaning is performed on the suction tool body 10, the brushed cloth 21 performs a high-speed sweeping operation on the cleaning surface near the left and right sides of the suction port 13, Dust swept up by the raised fabric 21
The suction work is sucked more immediately, and the cleaning operation can be performed more efficiently with respect to the reciprocating motion of the suction tool body 10.

[0018]

As described above, the suction device for an electric vacuum cleaner of the present invention is suitable for cleaning a wooden floor or a tatami mat.
By providing a rotatable rotating body that is inclined with respect to the surface to be cleaned, the wiping member on the lower surface of the rotating body can rub against the surface to be cleaned, so that the dust sweeping and wiping effects on the surface to be cleaned are sufficient. Can be demonstrated. Since the rotating body is provided on the left and right of the suction port, the dust swept out by the wiping member can be immediately sucked. Also, when cleaning the carpet, the rotating body rotates,
By reducing the frictional resistance between the main body of the suction tool and the surface to be cleaned, it is possible to perform a cleaning operation with a light operating force, and it is possible to provide a suction tool for an electric vacuum cleaner that has good operability, durability, and usability.

Further, the rotary shaft is inclined from the suction port side toward the left and right sides of the suction tool body, and the lower surfaces of the left and right rotating bodies are inclined in different directions with respect to the surface to be cleaned. If the left and right rotating bodies are tilted like a letter C, the base points of the left and right rotating bodies are the left and right outer end sides, and the rotating directions of the left and right rotating bodies on the suction port side of the suction tool body are the same. Becomes Therefore, the sweeping direction of the rotating body in the vicinity of the suction port is the same, and the dust swept out by the left and right rotating bodies smoothly flows into the suction port. When the left and right rotating bodies are inclined in a V shape, the moving direction of the suction tool body and the rotating direction in the vicinity of the suction opening of the left and right rotating bodies become the same, and the swept dust can be efficiently sent to the suction opening.
