Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a suction tool for bedding that is connected to the tip of a vacuum cleaner.

BACKGROUND ART Conventionally, suction devices of this type, particularly those for cleaning bedding such as futons and blankets, have been constructed as shown in FIGS. 5 and 6. That is, the connecting pipe 2 was rotatably attached to the suction tool main body 1, and the rotating roller 3 was rotatably held on the floor side of the suction tool main body 1, approximately in the center in the front-rear direction, with almost its full width. . This rotating roller 3 has a cylindrical base 4
and bosses 5, 6, and 7 with a diameter of approximately 5 mm and a height of approximately 10 mm protruding from this outer surface in the normal direction at an angle of 120 degrees to each other, and bosses 5, 6 located at a certain distance away from these. , 7 are formed by shifting the phase by 60 degrees around the central axis, and the bosses 8, 9, and 10 are formed by a large number of bosses formed sequentially in the same manner.

Also, as a general floor suction device,
The suction device described in the publication was devised.

Problems that the invention aims to solve: However, in the former suction device, the entire back side of the suction device body 1 becomes the suction port, so it sticks to the surface of the futon, and when moving back and forth, the single rotating roller 3, the suction device main body 1 has a disadvantage in that its front and rear surfaces dig into the bedding and cannot be operated.

In the latter case, the cylindrical body corresponding to the rotating roller is made of a soft material such as urethane foam, so even if you try to use this suction tool for cleaning bedding, the cylindrical body will be crushed by the suction force, and Since the front and rear surfaces of the suction device cover the cylindrical body, the front and rear surfaces of the suction device dig into the bedding and cannot be operated, as in the former case. Furthermore, since the left and right portions of the suction hole are covered with the futon, the area (area) that actually sucks the dust inside the futon becomes small, making it useless.

The present invention solves these drawbacks and provides a suction device for bedding that is easy to use.

Means for Solving the Problems In order to solve the above conventional problems, the present invention has a connecting pipe connected to the vacuum cleaner body on one side, and a suction port communicating with the connecting pipe on the bottom. The suction device is equipped with a main body of the suction device and a pair of rotating rollers that are arranged at the bottom of the main body of the suction device and rotate in contact with the surface of the bedding, and the suction port is positioned so as to protrude downward from the bottom of the main body of the suction device. Therefore, front and rear storage spaces are formed at the bottom of the main body of the suction tool and in front and behind the suction port, with the front and lower sides and the rear and lower sides open, and the rotating rollers are provided in these storage spaces, respectively. Further, the rotating roller has a plurality of small pillars arranged in a substantially equilateral triangular shape, each having a predetermined width in the longitudinal direction and extending in three directions, with a plurality of small pillars arranged in a row in a circumferential phase shifted in the longitudinal direction of the rotating roller. It was constructed by setting up

Function In the above configuration, the bedding is beaten by the rotating roller, and the dust thrown out by this is sucked through the suction port. Since rotor rollers are positioned before and after this suction port to support the surface of the bedding, the surface fabric of the bedding etc. does not penetrate deeply into the suction port.

Furthermore, since the storage space in which the rotor roller is arranged is open at the front and back, it does not dig into the outer material of the bedding during operation.

Since the wiper pillars are formed by arranging the vertices of ribs extending in three directions in a substantially equilateral triangle shape, the vertical displacement stroke of the ribs relative to the bedding surface is large, and the vertical displacement stroke between adjacent ribs is also large. From a certain point, the surface of the bedding becomes intricately patted in a so-called checkerboard pattern.

Also, even if the small piece itself is triangular,
When viewed as a whole, the ribs of adjacent trabeculae have a hexagonal shape, which allows for good rotation even on the bedding surface made of slippery fabric.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

In Figures 1 to 4, the bedding suction device main body 1
1 is a connecting pipe 12 for connecting to an extension pipe of a vacuum cleaner, and an upper suction tool 13 that rotatably holds this pipe.
The lower suction tool 14 is attached to the upper suction tool 13 from below, and the lower suction tool 13 is connected to the lower suction tool 13 before and after the suction port 15 formed approximately in the center of the lower suction tool 14 in the front-rear direction and covering almost the full width of the suction tool main body 11. It is composed of a pair of rotating rollers 16 rotatably held by a tool 14. To describe further, the suction port 15 is connected to the suction tool main body 11.
By protruding downward from the bottom of the suction tool main body 11, front and rear storage spaces A are provided at the bottom of the suction tool main body 11 and in front and behind the suction port 15, with the front and lower sides and the rear and lower sides open. , B are formed, and the rotating rollers 16 are arranged in these storage spaces A and B, respectively. The suction port 15 is connected to the rotating roller 1
It is wide at the top with a distance of approximately several mm from the outer circumferential diameter of the rotary roller 16, and gradually narrows toward the floor, and the tip is located approximately 5 mm above the floor surface of the rotating roller 16, and this front-to-back width is It is formed to approximately 5 mm. 17 is a plurality of ribs provided to partition the suction port 15, approximately 2 mm from the floor side tip of the suction port 15.
It is formed with the upper side as the lower end surface.

The rotating roller 16 includes a cylinder 18 serving as a base,
Approximately 5 mm protrudes from the surface of this cylinder 18 in the normal direction,
A small column 22 consisting of rib bodies 19, 20, and 21 having an axial length of approximately 20 mm, each formed at an angle of 120 degrees to each other, and having apexes arranged in a substantially equilateral triangle shape.
The lower suction tool 14
It is fixed to a rotating shaft 23 formed in a. Further, the front and rear surfaces of the lower suction tool 14 are open, and the rotating roller 16 is exposed.

Next, the operations and effects of the above configuration will be described.

When the connecting pipe 12 is connected to the extension pipe of the vacuum cleaner and the bedding suction tool 11 is moved forward and backward on the bedding such as a futon, the part between the rotating rollers 16 will be attracted to the suction port 15. It is lifted up and sucks up the dust inside the bedding. At this time, the suction port 15
As a result of regulating the amount of the outer fabric of the bedding sucked up inside by the plurality of ribs 17, the bedding will not be damaged even if the moving operation is performed rapidly.
In addition, the loud noises caused by the outer fabric moving in and out are also reduced, and no discomfort is caused. In addition, minute vibrations caused by the movement of the outer material in and out and rhythmic vibrations that the plurality of rib bodies 19, 20, 21 of the rotating roller 16 give to the bedding surface due to their rotation can prevent the inside of the bedding from becoming clogged. It effectively knocks out dust and increases the dust suction effect.
Furthermore, the action of the rotating roller 16 will be described in detail.

Since the small pillars 22 of the rotating roller 16 are formed by arranging the vertices of the rib bodies 19, 20, 21 extending in three directions in a substantially equilateral triangle shape, the vertical displacement stroke H of the rib bodies 19, 20, 21 with respect to the bedding surface
As shown in FIG. 1, the bedding is large and the vertical displacement stroke between adjacent rib bodies is also large, so the bedding is folded in a complicated manner in a so-called checkerboard pattern.

Furthermore, even if the small pillars 22 themselves have a triangular shape, when the ribs of the adjacent small pillars 22 are viewed as a whole, they have a hexagonal shape. It also rotates well.

Generally, in a rotating roller having a polygonal cross-section, the smaller the number of corners, the greater the futon beating effect, and conversely, the larger the number of corners, the smoother the roller rotates.
In other words, those on a flat plate with a rod-shaped cross section and beaters at both ends are excellent in terms of beating effect, but
Rotatability is extremely poor; conversely, those with square or larger angles have excellent rotatability, but
It is inferior in terms of knocking effect.

In this embodiment, the rib bodies 19, 20, and 21, which are arranged in a substantially equilateral triangular cross section, are alternately arranged with a phase shift in the circumferential direction, thereby achieving both a knocking effect and good rotational performance. It is.

In addition, since the front and back width of the suction port 15 is small, about 5 mm, even if a large vacuum pressure is applied to suck in dust inside the bedding due to the operation of a vacuum cleaner, the suction force is relatively small. Since the book is rotatably supported by rotating rollers 16, it can be easily moved.

Incidentally, the distance between the suction ports 15 in the front and back direction is narrow on the floor side and widens upward, so that the wind speed decreases above the suction ports 15, internal wind noise decreases, and noise also decreases. Moreover, since a substantially uniform vacuum pressure can be obtained over the entire widthwise area of the suction port 15, the width of the bedding suction tool 11 can be cleaned with a single back-and-forth movement operation, and cleaning can be performed efficiently.

Effects of the Invention As described above, the present invention consists of arranging a pair of rotating rollers that rotate on their own in contact with the bedding surface at the bottom of the suction device body, and positioning the suction port so as to protrude downward from the bottom of the suction device body. Therefore, front and rear storage spaces are formed at the bottom of the main body of the suction tool and in front and behind the suction port, with the front and lower sides and the rear and lower sides open, and the rotating rollers are provided in these storage spaces, respectively. Furthermore, these rotating rollers have a plurality of small pillars each having a predetermined width in the longitudinal direction and in which the vertices of rib bodies extending in three directions are arranged in a substantially triangular shape, with the phases shifted in the circumferential direction in the longitudinal direction of the same rotating roller. This structure has the following excellent effects as a suction device for bedding.

Since the small pillars of the rotating roller are formed by arranging the apexes of rib bodies extending in three directions in a substantially equilateral triangle shape, the vertical displacement stroke of the rib body with respect to the bedding surface is large, and the vertical displacement stroke between adjacent rib bodies is also large. Because of its large size, the surface of the bedding is beaten evenly from front to back, left to right, and in a complicated and reliable manner in a so-called checkerboard pattern.

Therefore, dust is reliably knocked out and bedding can be cleaned well.

Even if the trabeculae themselves are triangular in shape, if you look at the ribs of the adjacent trabeculae as a whole, they will have a hexagonal shape, which makes them comfortable even on bedding surfaces made of slippery fabric. Rotate to .

Therefore, smooth rotation can be obtained, and the dust removal characteristics can be further improved. Also, since it rotates smoothly, it does not cause damage to bedding, etc.

Since the storage space in which the rotating rollers are placed is open to the front and rear, the front and rear of the suction device do not dig into the outer fabric of the bedding. As a result, good operability can be obtained, and damage to bedding and the like can also be prevented in this respect.

Since the rotating rollers are located before and after the suction port, the bedding surface fabric does not get deep into the suction port, which reduces the operating force. In addition, since the bedding surface fabric etc. vibrate with respect to the suction port due to the ribs in the rotating roller, dust absorption can be further improved.
