Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner, and more particularly to a combination of a dust suction head and its pipe.

Conventionally, a broom sweeping tool has traditionally existed in Japan, but the difference with the suction head of the current vacuum cleaner is that the broom is easy to use in an upright posture and coaxial with the tip. Grab a straight handle and swing your arm to sweep your feet from side to side or backward to sweep away dust and collect it collectively, while the latter was attached by bending it diagonally so that the head touches the floor surface. The pipe handle pushes the dust to the dust area, and the head is moved forward and backward with respect to the floor, away from the feet, back and forth at the waist, and the dust is sucked and collected. This latter work style using the waist has adopted the Western lifestyle into Japan, and has become a habit, and there are no examples of discussing the irrationality of this work mode, and the current trends in vacuum cleaner technology are exclusively. It depends on the increase of suction power of the vacuum cleaner body and the improvement of the head for scrubbing dust. It is natural that the vacuum cleaner main body has to be increased in size because the conventional technology that relies only on the vacuum suction force to remove the dust stuck to the carpet or the like requires a considerably high vacuum. To solve this, mechanical peeling, i.e. scraping, of rotating the brush in the head is effective, but this time the weight of the head increases. As described above, both the weight and the suction force of the head itself are increasing, and the cleaner moves the head in a mid-waist posture against this, and thus the burden becomes even greater. There is also a proposal to lengthen the pipe so that if the distance between the head and the person is lengthened, it will be easier for the worker to take an upright posture, but this is a mistake, and in fact the force moment when changing the direction of the head becomes more and more. As it gets bigger, the burden on the waist is increasing. A solution that attempts to reduce the suction force temporarily to reduce the burden on the operator is just a backward technology. However, it is said that cleaning is the most burdensome task for housewives in recent years, and the number of patients with back pain is increasing, but neglecting ergonomic research, that is, research on the working style of vacuum cleaners, It can be said that there is a problem in the technical trend of the industry that concentrates on improving only the hardware side and does not revisit the origin. The most remarkable point in this kind of technological trend is
In the conventional head structure, the cleaning direction is considered only in the front direction and not in the rear direction or the left-right direction. In the present invention, the work to move forward is inevitably a middle-waist posture, but if the sweep direction is backward, left-right direction, it is almost an arm movement like a traditional parlor broom, and the waist is excessively negative. It focuses on the fact that there is no refusal. As a conventional head that can be applied to the present invention, there is a lightweight head made by bundling several thin suction tubes to scrape it out manually, but it is not possible to clean a large area or collect a large dust.
Also, the suction resistance is large and it is easy to get clogged, so to prevent this,
Again, the size of the vacuum cleaner body must be increased. Further, the work of replacing such a head is also troublesome.

The present invention confronts the above-mentioned technical trend, and makes the vacuum cleaner head extremely lightweight and can handle the dust around the feet like a broom by manually scraping it up. That is, replacing the head by the movement of the waist in the conventional type with a combination of the head and the handle by the movement of the arm, the volume of the vacuum cleaner body is reduced, and at the same time, it is possible to clean a large area and a narrow gap without replacing the head. It is possible to collect large garbage and reduce the burden on workers.

[Means for Solving the Problems] As a vacuum cleaner head, an elastic repellent tip bundle is arranged in a hollow, and a suction pipe extending from the bundle is used as a handle of the tip bundle, and is gripped almost vertically with one or both hands. The dust is scraped up and swept up by sweeping the tip bundle to the left and right or backward. This work is an arm movement, not a conventional hip flexion movement. At this time, since the tip bundle has elasticity, it repels dust and is also repelled by dust in the vine. Thus, the dust suspended in the air is effectively sucked into the hollow portion even in a low vacuum.

BEST MODE FOR CARRYING OUT THE INVENTION In a vacuum cleaner comprising a dust suction head, a vacuum cleaner body, and a pipe connecting these heads, a repellent tip bundle is arranged as a head and the tip length is The length of the pipe so that dust is repelled and swept by the movement of the head, and one end of a rigid straight pipe is connected to the hollow part as a handle in the same direction as the tip, and the length of the pipe is grasped by both hands. The length of the head is set so that it can be swept under the feet, and the other end of the pipe is connected to the main body of the vacuum cleaner through a flexible pipe. Hereinafter, this embodiment will be described in detail with reference to the drawings. FIG. 1 is a schematic view of a vacuum cleaner showing an embodiment of the present invention, in which a head portion is partially cut away.
A flexible pipe 2 is extended from a conventional vacuum cleaner body 1 as in the conventional case, and a rigid elbow 10 is fixedly connected to the end of the flexible pipe 2, and the other end of the elbow 10 is a straight rigid pipe 5.
The other end of the pipe 5 is detachably connected to a rigid pipe 5'coaxial with the pipe 5 by a connecting ring 4 and is connected to the end through a rotatable connecting ring 3 and 5 ', 6, 7, 8, and 9 A vacuum suction head assembly composed of the above is connected. The head assembly is composed of a rigid crown portion 6, a rigid pipe 5'standing right above the center of the crown portion 6, an outer skirt 7 and an inner skirt 8, 8'extending downward from the lower edge of the crown portion 6, and these skirts. Resilient tip tip bundle 9 clamped and fixed between
9 '. Each of the resilient tip tips, the outer skirt and the inner skirt has a single annular shape, and the head is made horizontally elongated as shown in FIGS. 3 and 2 showing AA cross section and BB cross section of FIG. As shown in FIG. 1, the vacuum suction pipes, that is, the handles 5 ', 5 extend from the center portion thereof at right angles to the head. The outer skirt and the inner skirt are flat rings (FIG. 2) having substantially the same elasticity, between which the root of the tip bundle is firmly held and elastically fitted to the lower edge of the crown portion 6. Of these, the outer skirt assists the resilience of the tips, corrects the habits that tend to occur in the tip bundles, and secures a hollow portion so that even large dust can be sucked. The tip bundles are arranged in a row to form a hollow portion having a narrow rectangular cross section (Fig. 2). The tip bundles 9 and 9'on each long side have different lengths (Fig. 3). Moreover, the tip bundle 9 having the shorter tip bundle length is trimmed into a crescent shape (FIG. 1) so that the central portion is slightly shorter, so that dust can be effectively taken into the hollow portion without being scattered when sweeping. . The arrow 11 indicates the head sweep direction. As can be seen from the cross section of FIG. 3, the hanging length of the outer skirt 7 is the same on the left and right sides of the drawing, but the inner skirts 8 and 8'are made different according to the tip bundle length. Moreover, the tips of both short sides of the narrow rectangle are convenient for entering the narrow gap and scraping out dust.

According to the present invention, since the portability of the head is extremely improved, only the surface area required for cleaning can be cleaned efficiently. Since the conventional head is heavy, it is often slid and carried over the unnecessary surface area to be cleaned. Even in the sweeping operation using a traditional broom, the dust on the area requiring cleaning was swept while sweeping over the area where cleaning is unnecessary, but according to the present invention, local cleaning is performed. Easy to clean and the efficiency of cleaning work will be dramatically increased. As shown in FIG. 1, in the case of using as a parlor broom in which the pipe is lengthened and the handle is gripped and swept by both hands, for example, one part of the pipe 5 is held near the elbow 10 and the other hand is used to grip the pipe 5 '. Since the elbow 10 can be held in an upright posture and the elbow 10 is still rotatable, the head can be freely rotated without the hassle of the direction of the flexible pipe, and the work form as a parlor can be adopted, and the middle waist posture is unnecessary. Become. According to the present invention, the head is extremely light and it is a work of simply swinging the arm to the left and right or backward, and it is not a flexion motion of the waist. Therefore, the rigid pipe 5 is removed to shorten the handle and make it like a one-handed broom. Even if the sweep is repeated in the middle waist, it does not burden the waist. Conventionally, the vacuum suction, which had previously been forced to increase the size of the vacuum cleaner body due to dust being scraped out, was replaced by scraping by human power, and as a result, the vacuum cleaner body only needs to be a small machine, reducing the total rejection of the cleaner. To do. According to an experiment conducted by the present inventor, it has been found that a vacuum cleaner body can be practically used even if it is a shoulder-mounted small machine. In order to clean a narrow gap or a sill, it was inconvenient to replace the floor head with the gap head in the conventional head, but in the present invention, the short side tip of the narrow rectangular tip tip bundle is especially in the gap. Easy to put in, dust can be scraped out and suctioned, and head replacement is unnecessary.
