In a side part, a side direction flow route 16 is provided. then, the both ends of the napped cloth 14 are R-shaped so that the dust can smoothly flow into the sucking groove 12.

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.

2. Description of the Related Art Conventionally, this type of floor suction device has been disclosed in, for example, Japanese Patent Application Laid-open No. 66-1096.
As shown in Publication No. 7. ! 4. The structure shown in Figure 6 has become common, and was used to clean carpets, floors, and folding surfaces, respectively, by switching between ku and betaru.

That is, when used on a hard flat surface such as a floor or a folding surface, the cup 1 is made to protrude beyond the lower suction tool 2 by operating the handle, and the lower surface of the lower suction tool 2 is supported by the roller 3 and the brush 1. This makes it stand out from the cleaning surface. In this state, the gap between the lower surface of the lower suction tool 2 and the cleaning surface is set to about one fin, so that even if fine sand or the like is sucked in, the floor surface etc. will not be damaged.

In addition, in the structure shown in FIG. 6, brush bristles 6 made of nylon thread with diameter of about 0.16 mm are attached to the outer periphery of the lower suction tool 4.
A suction device specifically designed for tatami mats and tatami mats was also considered.

Problems to be Solved by the Invention However, when using this type of structure on a hard flat surface such as a wooden floor or folding surface, the focused and hardened brush body will not touch the wooden floor. Because the surface is rubbed, there are countless small scratches, which is a serious problem in terms of appearance, especially for wax-treated items.
At the same time, when operated, it felt like rubbing, resulting in a poor cleaning experience. There were also problems with traces of roller movement and rumbling noises during movement.

In the case of folding surfaces, there are quality problems such as the brush body scraping off the outer skin of the rush that forms on the entire folding surface, and problems such as the unpleasant noise caused by scraping the folding surface during cleaning. There was a strong desire to improve the difficulty in handling the tatami mats, the poor operating feel, and the unpleasant noises that could damage the tatami mats.

Therefore, the object of the present invention is to improve the operating feel and prevent damage to hard surfaces such as wooden floors and folding surfaces, similar to the action of wiping a rag through the action of a raised cloth.

Means for Solving the Problems In order to solve these conventional problems, the present invention provides a structure in which a bank-like mounting seat is formed on the outer periphery of a lower suction device having all suction ports for sucking dust, etc. The seat is constructed by attaching a raised cloth made of cut pile-like spun cloth.

Function: In the structure of the present invention described above, since the raised fabric made of cut pile-shaped spun cloth is formed on the embankment-shaped mounting seat formed on the outer periphery of the lower suction tool, when it comes into contact with the surface to be cleaned, On the other hand, the touch of contact is soft and blends well, so it acts like wiping the surface with a rag.This protects hard surfaces such as wooden floors and folding surfaces from scratches and improves slipperiness. The unpleasant noise of time will also disappear.

Furthermore, the action of polishing a hard flat surface also occurs.

Example Examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 to 3, the suction tool main body 6 is the upper suction tool 7.
and a lower suction device 8, 9 is a pipe and an extension tube connected to the suction side of the vacuum cleaner body via a hose is detachably connected, and a ring 10 is attached to the upper suction device 7.
It is rotatably attached. A suction port 11 is formed approximately in the center of the lower suction tool 8, communicates with the pipe 9, and forms a suction groove 12 extending from the suction port 11 to the left and right ends of the lower suction tool 8.

A bank-like mounting seat 13 is formed on the front and rear and outer periphery of the suction groove 12. Reference numeral 14 denotes a raised fabric, which is made of a pile-shaped spun fabric. Fixed with adhesive. The pile thickness of the raised fabric 14 is made of ultrafine fibers of 0.1 or less and is formed at high density. In order to avoid contact with the surface to be cleaned, and to reduce the contact resistance with the surface to be cleaned and make it slippery during operation, the length is set to 4 to 6 inches, and it has a softness that cannot be obtained with conventional plan bristles or rollers. I'm getting a feel for it.

1. Regarding the mounting arrangement of the raised fabric 14, please refer to the suction device body 6.
A suction passage 1 is provided between the raised fabric 14 and the raised fabric 14 in the front part.
6 is formed to ensure and improve the dust suction performance of the front corner. By adjusting the height of the upper surface of the suction passage 16, the dust suction performance can be completely changed as desired. In the rear part, a raised fabric 14 is integrally formed to have almost the same longitudinal length as the lower suction tool 8, and the tightness of the suction groove 12 is improved and the suction pressure is increased to remove dust from the grooves of the surface to be cleaned. Improves performance. Furthermore, regarding the side part, the side inflow passage 1 is designed so that the side dust suction airflow of the lower suction tool 8 flows into the suction groove 12 section at high speed to ensure and improve the side dust suction performance.
There are 6. Incidentally, the dust suction performance can be varied by changing the height, shape, etc. of the side inlet passage 16 and adjusting its opening cross-sectional area.

Furthermore, the shapes of both ends of the raised fabric 14 are such that the front side of the suction tool main body 6,
It is formed into a rounded and smooth shape so that the dust sucked in from the side can smoothly flow into the suction groove 12 without getting caught on the edge of the raised cloth 14.

Next, the operation of the configuration of this embodiment will be explained. Now, when connecting and fixing the pipe 9 of the suction tool main body 6 to an extension pipe via a hose connected to the vacuum cleaner main body, and cleaning the surface to be cleaned such as a wooden floor or a cushion floor, the lower suction tool The tip of the raised cloth 14 adhesively fixed to the mounting seat 13 of 8 comes into contact with the wooden floor surface and slides in accordance with the cleaning movement back and forth. At this time, since the material in contact with the wooden floor surface is a cut-pile spun cloth made of ultra-fine fibers, the raised cloth 1
40 The elasticity is extremely soft, the contact sliding is soft and it moves smoothly on the wooden surface.

Therefore, the feeling of movement is extremely smooth, and there is no chance of getting stuck.
Abnormal sliding noise is eliminated. The raised cloth 14 itself has the effect of wiping the wooden floor surface, and the effect of polishing the entire wooden floor surface is achieved. Furthermore, even when moving over solid foreign matter such as sand grains, the pile length of the raised fabric 14 is set to 4 to 6 gourds, so the sand grains are pushed into the dense pile.
By rolling it over, the wooden floor surface is not pressed too hard and can be prevented from being scratched.

Dust on the front and side parts of the suction device main body 6 can also be removed from the suction passage 16. The dust is sucked into the side inflow w116 into the suction groove 12 at high speed, and by cleaning the dust in an area larger than the width of the suction tool body 6, the efficiency of cleaning work can be greatly improved. .

Next, when cleaning the folding surface, the same effect as the wooden floor surface described above is performed, but in particular, the cut pile part of the ultra-fine fibers forming the raised cloth 14 is removed from the grass that forms the folding surface. As the piles come into contact sequentially, the force of rubbing against the grass surface is dispersed, and since the pile has low elasticity, it acts as if it were sliding on the sides of each pile, resulting in an extremely smooth operating feel due to the reduced sliding resistance. At the same time, it is possible to prevent the surface of the rush from being scratched. In addition, since the pile forming the raised cloth 14 is extremely fine and dense, the tip of the pile can fully penetrate between the grasses on the folding surface, allowing dust to be completely removed, resulting in efficient and hygienic cleaning. It is something that can be used for work.

Effects of the Invention As described above, the present invention forms an embankment-like mounting seat on the outer periphery of a lower suction device having a suction port for sucking in dust, etc., and a raised fabric made of cut pile-like spun cloth is placed on the mounting seat. It is a wooden floor. When sliding in contact with the surface to be cleaned, such as a folding cloth, the elasticity of the raised fabric is extremely soft, reducing sliding resistance and providing smooth operability and feel.This prevents stuck operations and abnormal sliding. This eliminates the sound.

Furthermore, the wiping action of the nap cloth itself also produces the effect of polishing the surface to be cleaned.

In addition, the pile that forms the entire surface of the raised cloth is extremely fine and dense, so even if solid foreign objects such as sand particles are pushed into the pile without pressing too hard against the surface to be cleaned, it can be used to prevent damage or to clean the surface of straw grass. It also has the effect of preventing scraping and blowing out dust between the grass. This provides a good cleaning feel, prevents damage, and allows for hygienic and efficient cleaning work.
