Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction device for an electric vacuum cleaner, and relates to a structure of the suction device suitable for cleaning a floor surface and a fold.

2. Description of the Related Art Conventionally, this kind of bed suction device is disclosed in, for example, Japanese Patent Application Laid-Open No. 55-1096.
As shown in Japanese Patent Laid-Open No. 7, the structure shown in FIGS. 4 and 5 is generally used, and is properly used so that the carpet surface, the floor, and the folding surface can be cleaned by switching the petal or the like. It was

That is, when using on a hard flat surface such as a floor surface or a folding surface, by operating the petal, the brush 1 is made to protrude from the lower suction tool 2, and the lower surface of the lower suction tool 2 is supported by the roller 3 and the brush 1. It is raised 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 1 mm so that the floor surface or the like is not damaged even if fine sand or the like is sucked.

Further, in the structure shown in FIG. 5, a wooden floor in which brush bristles 5 made of nylon thread having a diameter of about 0.15 mm are planted on the outer peripheral portion of the lower suction tool 4, and a suction tool dedicated to folding is also considered.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a structure, when used on a hard flat surface such as a wooden floor surface or a folding surface, first, on the wooden floor surface, the focused and hardened brush body is a wooden floor. Since the surface is rubbed, a number of fine scratches are present, and particularly the wax-treated product has a serious problem in appearance, and at the same time, it has a rubbing feel at the time of operation and a bad cleaning feeling. In addition, the movement traces of the rollers and the rumbling noise of the movements have been problems.

Even in the case of a foldable surface, the brush body forms a foldable surface, such as scraping off the outer skin of the strawberry, and the problem of unpleasant noise that rubs the foldable surface during cleaning, especially when operating from the direction orthogonal to the strawberry. There has been a strong demand for improvement in time lag, uncomfortable feeling of operation, and unpleasant noise that damages the folding.

Therefore, an object of the present invention is to improve the feeling of operation and prevent damage to a hard flat surface such as a wooden floor or a folding surface by the action of a raised cloth, like a cloth purse.

Means for Solving the Problems In order to solve such a conventional problem, the present invention provides a suction groove formed in the bottom left and right direction of the suction tool body in communication with the suction port, and along the front and rear of the suction groove. A mounting seat provided on the bottom of the main body of the suction tool so as to be located, and a raised cloth made of a cut pile-shaped spun cloth provided on the mounting seat, and there are a plurality of mounting seats located on the front side of the suction groove. In addition to being provided independently, a suction passage is formed between the ends of the adjacent mounting seats, and a lateral inflow passage is provided by opening the outside between the front and rear mounting seats.

Action In the above-described configuration of the present invention, the bank-shaped mounting seat formed on the outer peripheral portion of the lower suction tool is configured with the raised cloth made of the cut pile-shaped spun cloth, so that when the surface is in contact with the surface to be cleaned, On the other hand, since the contact feeling is soft and fits well, it acts like wiping the surface, which improves scratch protection and slipperiness on hard flat surfaces such as wooden floors and folding surfaces, as well as operation. It also eliminates the unpleasant sound of time.
Further, the action of polishing a hard plane is also generated.

Examples Examples will be described below with reference to the accompanying drawings. Fig. 1 ~
In FIG. 3, the suction tool body 6 is obtained by combining the upper suction tool 7 and the lower suction tool 8, and 9 is a pipe, which is an extension pipe communicating with the suction side of the vacuum cleaner body via a hose. It is detachably connected and is rotatably attached to the upper suction tool 7 by a ring 10. Reference numeral 11 denotes a suction port which is formed substantially in the center of the lower suction tool 8 and communicates with the pipe 9.
Further, suction grooves 12 extending to the left and right ends of the lower suction tool 8 are formed.

Before and after the suction groove 12, a bank-shaped mounting seat 13 is formed on the outer peripheral portion. Reference numeral 14 is a raised cloth, which is made of a cut pile spun cloth and is adhesively fixed to the upper surface of the mounting seat 13. Has been done. The pile thickness of the napped cloth 14 is made of ultrafine fibers of 0.1 or less and is formed at a high density. Regarding the pile length, the suction tool body 6 is attracted to the surface to be cleaned during the cleaning work and the mounting seat 13 To prevent it 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 to make it slippery, set a length of 4 to 6 mm, giving a soft feel that cannot be obtained with conventional brush bristles or rollers. It has gained.

Also, regarding the mounting arrangement of the raised cloth 14, the suction tool body 6
Of the suction passage 1 between the raised cloth 14 and the raised cloth 14.
A plurality of 5 are formed to secure and improve the dust absorption performance at the front corner. Further, the dust suction performance can be arbitrarily changed by adjusting the height of the upper surface of the suction passage 15. In the rear part, a raised cloth 14 is integrally formed to have substantially the same length as the longitudinal direction of the lower suction tool 8, and the tightness of the suction groove 12 part is improved to increase the suction pressure to collect dust such as the groove part of the surface to be cleaned. It has improved performance. Further, regarding the side portion, the side suction passage 16 is provided in order to ensure and improve the side dust suction performance by allowing the dust suction airflow to flow into the suction groove 12 at a higher speed than the side of the lower suction tool 8.
Is provided. The dust suction performance can be varied by changing the height, shape, etc. of the lateral inflow passage 16 and adjusting the opening cross-sectional area thereof.

Furthermore, the shape of both ends of the raised fabric 14 is in front of the suction tool body 6,
The R-shaped and smooth shape is formed so that the dust sucked from the side can be smoothly introduced into the suction groove 12 without being caught by the end of the raised fabric 14.

Next, the operation of the configuration of this embodiment will be described.
When the pipe 9 of the suction tool body 6 is connected and fixed to an extension tube via a hose connected to the electric vacuum cleaner body, and when cleaning a wooden floor or a cushion floor, which is the surface to be cleaned, the lower suction tool 8 The tip portion of the raised cloth 14 that is adhesively fixed to the mounting seat 13 comes into contact with the wooden floor surface and slides in accordance with the front and rear cleaning operation. At this time, since the contact with the wooden floor surface is the cut-pile-shaped spun cloth formed of the ultrafine fibers, the elasticity of the raised cloth 14 is extremely soft, and the sliding contact is soft and the wooden floor surface is smoothly moved. To do.

Therefore, the feeling of movement is extremely smooth, it gets stuck,
Abnormal sliding noise is eliminated. Further, the raised cloth 14 itself has an effect of wiping and cleaning the wooden floor, and has an effect of polishing the wooden floor. Furthermore, even when it moves over solid foreign matter such as sand grains, the pile length of the napped cloth 14 is set to 4 to 6 mm, so that sand grains are pressed into the dense pile and pressed firmly against the wooden floor surface. It is possible to prevent scratches without being damaged.

Dust in the front and side portions of the suction tool body 6 is also sucked and sucked into the suction groove 12 at high speed from the suction passage 15 and the side inflow path 16, and the dust suction range is greater than the width dimension of the suction tool body 6. By doing so, the efficiency of the cleaning work can be greatly improved.

Next, when cleaning the folding surface, the same operation as that of the above-mentioned wooden floor surface is performed, but especially for the strawberries forming the folding table, the cut pile portion of the ultrafine fibers forming the raised cloth 14 is formed. As they contact each other in sequence, the rubbing force on the surface of strawberries is dispersed, and since the elasticity is low, they act like sliding on the side surface of each pile, and the sliding resistance is reduced, resulting in an extremely smooth feeling of operation. At the same time, the phenomenon of scraping of the surface of strawberries can be prevented. In addition, since the pile forming the napped cloth 14 is extremely fine and has a high density, the tip of the pile can fully enter between the straw mats on the folding table, and dust can be completely expelled for efficient and hygienic cleaning. You can work on it.

As described above, according to the present invention, a bank-shaped mounting seat is formed on the outer peripheral portion of the lower suction tool having a suction port for sucking dust and the like, and a raised cloth made of a cut pile spun cloth is formed on the mounting seat. It is an attached structure, and when it slides in contact with the surface to be cleaned, such as a wooden floor or a fold, the elasticity of the raised fabric is extremely soft, and the smooth sliding operability and feel can be obtained by reducing the sliding resistance. It is possible to eliminate the jamming during operation and abnormal sliding noise.

Further, the brushed cloth itself wipes and cleans the surface to be cleaned.

Furthermore, since the pile that forms the raised fabric is extremely fine and has a high density, even solid foreign matter such as sand particles can be pushed into the pile without being pressed strongly against the surface to be cleaned, preventing damage or preventing the surface of the strawberries from being scraped. There is also a dust-expulsion effect between the straw and the grass. As a result, the cleaning feeling is good, damage can be prevented, and hygienic and efficient cleaning work can be performed. Further, since the high-speed airflow flows in through the suction passage between the front mounting seats and the side inflow passage between the front and rear mounting seats, the dust absorption characteristic is improved and the cleaning range can be expanded.
