Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor suction tool for a vacuum cleaner, and relates to a structure of the suction tool suitable for cleaning floors and tatami mats.

BACKGROUND OF THE INVENTION As shown in FIGS. 5 and 6, this kind of floor suction device is made of a cut pile-shaped spun cloth on the outer peripheral bottom surface 3 of a lower suction device 2 having a suction port 1 for sucking in dust, etc. A raised cloth 4 was provided, and the raised cloth 4 was composed of ultrafine nylon threads having a diameter of 0.1 m or less.

Problems to be Solved by the Invention However, with such a structure, there are advantages such as improving the operating feel and preventing scratches on hard surfaces such as wooden floors and tatami mats by the action of the raised cloth 4 like a rag. However, since the raised fabric 4 is made of fine fiber nylon yarn, it has poor durability.

The present invention solves this problem and provides an extended period of use of an excellent suction tool that improves the operating feel and prevents scratches on hard surfaces such as wooden floors and tatami surfaces by the action of a raised cloth, similar to a rag. With the goal.

Means for Solving the Problems To solve these conventional problems, the first means of the present invention is to provide a cut that is supported by a support on the bottom surface of the outer periphery of a lower suction device having a suction port for sucking in dust, etc. A raised fabric made of pile-like spun fabric is provided, and the raised fabric is composed of a plurality of initial use fabrics and a plurality of replacement fabrics. The initially used raised fabric and the replacement raised fabric are supported on the outer peripheral surface with an adhesive or the like.

Effects In the above-mentioned means of the present invention, the first means is to provide a raised fabric made of cut pile-shaped spun cloth supported by a support on the bottom surface of the outer peripheral part of the lower suction device having a suction port for sucking in dust, etc. The raised cloth is composed of multiple initially used raised cloths and multiple replacement raised cloths, so even if the initially used raised cloth is worn out due to friction with a non-cleaning surface, the support can be turned over and replaced. The second method is to use a blanket to clean non-cleanable surfaces and ensure twice the durability of the conventional method.The second method is to make the support body a polygonal column and glue the initially used raised cloth and the replacement raised cloth to the outer peripheral surface. Even if the initially used raised cloth wears out due to friction with the non-cleaning surface, by rotating the polygonal column support, it is possible to clean the non-cleanable surface with a replacement raised cloth, compared to the conventional method. N times the durability (4 times in the case of a square prism) can be ensured.

Example The first embodiment will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, the suction tool main body 5 is the upper suction tool 6.
and a lower suction device 7, 8 is a pipe and an extension pipe connected to the suction side of the vacuum cleaner body via a hose is detachably connected, and a ring 9 is attached to the upper suction device 6.
It is rotatably attached. A suction port 10 is formed approximately in the center of the lower suction tool 7, communicates with the pipe 8, and forms a suction groove 11 extending from the dynamic suction port 10 to the left and right ends of the lower suction tool 7.

Embankment-shaped mounting seats 1 are provided on the bottom surface of the outer periphery before and after the suction groove 11.
2 is formed on the support body 13, and the screw 14 is attached to the lower suction lower.
It is installed at. Reference numeral 15 designates a plurality of initially used raised fabrics formed in the longitudinal direction of the support 13, which are made of cut pile-shaped spun fabric and are adhesively fixed to the upper surface of the mounting seat 12. Reference numeral 16 designates a plurality of replacement raised fabrics formed on the back side of the plurality of initially used napped fabrics 15 formed in the longitudinal direction of the support 13. Like the initially used napped fabrics 15, they are made of cut pile-shaped spun fabric, and are attached to the mounting seat 12. It is glued and fixed to the back of the.

The pile thickness of the initially used raised fabric 15 and the replacement raised fabric 16 is made of fine fibers of 0.1 W or less and is formed with high density. The pile length is designed to prevent the suction tool main body 5 from being attracted to the surface to be cleaned during cleaning and to prevent the mounting seat 12 from coming into contact with the surface to be cleaned, and to reduce the contact resistance with the surface to be cleaned during operation and make it slippery. It is set to a length of 4 loaves or more to give it a soft feel.

Regarding the installation and arrangement of the initially used napped fabric 15 and the replacement napped fabric 16, the front part of the suction device main body 5 is located between the initially used napped fabric 15 and the initial used napped fabric 15 and the replacement napped fabric 16. A plurality of suction passages 17 are formed between the front corner and the replacement raised fabric 16 to ensure and improve dust suction performance at the front corner. By adjusting the height of the upper surface of the suction passage 17, the dust suction performance can be changed as desired.

In addition, in the rear part, the initial raised fabric 15 and the replacement raised fabric 16 are made approximately equal in length to the longitudinal direction of the support 13, and the suction groove 1
By improving the tightness of the first part and increasing the suction pressure, the dust suction performance of the grooves on the surface to be cleaned is improved. Further, regarding the side portions, side inflow passages 18 are provided in order for the dust suction airflow to flow into the suction groove 11 portion at high speed from the sides of the lower suction tool 7 to ensure and improve the dust suction performance on the sides. Note that the dust suction performance can be varied by changing the height, shape, etc. of the side inlet passage 18 and adjusting the opening cross-sectional area. Furthermore, the shape of both ends of the initially used napped fabric 15 and replacement napped fabric 16 is smooth so that dust collected from the front and rear of the suction device body 5 does not get caught on the ends of the initially used napped fabric 15 and replacement napped fabric 16. It is formed into a rounded and smooth shape so that it can flow into the suction groove 11.

Next, the operation and effect of the configuration of this first embodiment will be explained. When the pipe 8 of the suction device body 5 is connected to an extension pipe via a hose connected to the vacuum cleaner body, and the surface to be cleaned such as a wooden floor or cushion floor is cleaned, the mounting seat of the lower suction device 7 The tip of the initially used raised fabric 15 adhesively fixed to 12 contacts the wooden floor surface and slides in accordance with the back and forth cleaning motion. At this time, since the material in contact with the wooden floor surface is a cut pile-like spun cloth made of fine fibers, the elasticity of the initially used raised fabric 15 is extremely soft, and the softness may be lost when it comes into contact with a non-cleanable surface. The touch of contact is soft and blends well with the surrounding surface, so it acts like wiping the surface with a rag.

However, since the initially used raised fabric 15 is made of fine fibers, its durability is limited, and it eventually wears out due to wear and the like. Therefore, the screw 14 is removed and the support body 13 is turned over so that the replacement napping cloth 16 can be brought into contact with the non-cleaning surface.
Tightening 4 attaches the support body 13 to the lower suction lower.

By this operation, the replacement raised cloth 16 is changed to the initially used raised cloth 1.
5 can be used in the same way.

Next, a second embodiment will be described with reference to the accompanying drawings.

In FIGS. 3-4. The suction tool main body 20 is obtained by combining an upper suction tool 21 and a lower suction tool 22,
3 is a vibrator, and an extension pipe connected to the suction side of the vacuum cleaner body via a hose is detachably connected to the upper suction tool 21.
It is rotatably attached to the ring 24 by a ring 24. A suction port 25 is formed approximately at the center of the lower suction tool 22 and communicates with the vibrator 23, forming a suction groove 26 extending from the suction port 25 to the left and right ends of the lower suction tool 22.

Embankment-shaped mounting seats 2 are provided at the front and rear of the suction groove 26 and at the bottom of the outer periphery.
7 is connected to the lower suction port 2.
It is supported by a angular projection 29 provided on 2. The angular protrusion 29 engages with an angular recess 30 of the support 28 . Reference numeral 31 denotes a holding portion of the lower suction tool 22, which maintains the engagement between the angular protrusion 29 and the angular recess 30 by elastic force. 3
Reference numeral 2 denotes a plurality of initially used raised fabrics formed in the longitudinal direction of the support body 28, which are made of cut pile-shaped spun fabric, and are adhesively fixed to the upper surface of the mounting seat 27. Reference numeral 33 designates a plurality of replacement raised fabrics formed on the back and side surfaces of the plurality of initially used napped fabrics 32 formed in the longitudinal direction of the support body 28. Like the initially used napped fabrics 32, they are made of cut pile-shaped spun fabric, and are It is adhesively fixed to the back and side surfaces of the body 28.

The pile thickness of the initially used raised fabric 32 is made of fine fibers of 0.1 ta or less and is formed with high density.

The pile length is designed to prevent the suction tool main body 20 from being attracted to the surface to be cleaned during cleaning and to prevent the mounting seat 27 from coming into contact with the surface to be cleaned, and also to reduce the contact resistance with the surface to be cleaned during operation and make it easier to slip. Therefore, the length is set to 4 mg or more to obtain a soft feel.

Next, the operation and effect of the configuration of this second embodiment will be explained. When the vibrator 23 of the suction tool body 20 is connected and fixed to an extension pipe via a hose connected to the vacuum cleaner main body, and the surface to be cleaned, such as a wooden floor or a cushion floor, is cleaned, the lower suction tool 22 is attached. The tip of the initially used raised fabric 32 adhesively fixed to the seat 27 comes into contact with the wooden floor surface and slides back and forth in accordance with the cleaning motion. At this time, since the material in contact with the wooden floor surface is a cut pile spun cloth made of fine fibers, the elasticity of the initially used raised fabric 32 is extremely soft, and the softness may be lost when it comes into contact with a non-cleaning surface. The touch of contact is soft and blends well with the surrounding surface, so it acts like wiping the surface with a rag.

However, since the initially used raised fabric 32 is made of fine fibers, its durability is limited, and it eventually wears out due to wear and the like. Therefore, the support part 31 of the lower suction port 22 is
The angular projection 29 and the angular recess 30 are opened in the direction, and the engagement between the angular projection 29 and the angular recess 30 is released, and at the same time, the support body 28 is rotated by 90 degrees, and the support 31 is returned in the direction opposite to the arrow A. The replacement nap cloth 33 can be brought into contact with the non-cleaning surface. By repeating this operation, the replacement napkin 3
