[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner mainly used for home use, and in particular, a dust collector main body is slidably provided on an operating rod, and the vacuum cleaner main body has a small and lightweight suction function. The present invention relates to an electric vacuum cleaner that employs a high cyclone suction device.

[0002]

2. Description of the Related Art Conventionally, an intake port for sucking dust at one end,
As an electric vacuum cleaner having an operating rod having a handle portion at the other end and a dust collecting portion for accumulating dust sucked from the air intake portion together with air, the dust collecting portion is slidable on the operating rod. The one provided is known (Japanese Patent Laid-Open No. 2-74255).
In the above-described known vacuum cleaner, the suction port is locked to one end of the operating rod, and the cleaner main body that filters the air flow containing dust with a cloth bag to remove dust is a hollow cleaner that forms an intake passage. Operating rod 3
Is slidably locked to. Then, when cleaning the floor surface, the main body of the vacuum cleaner is fixed to a position near the intake port on the operating rod, and cleaning is performed at that position. Also, when cleaning gaps, etc., place the cleaner body at a position farther from the intake port,
That is, the operation rod is moved to a position close to the upper end thereof, and the cleaner main body is configured so that the suction port portion is inserted into the skimmer so as not to interfere with the surroundings for cleaning. In this conventional example, due to the above-mentioned configuration, there are a normal cleaning for cleaning a large place and a temporary cleaning for cleaning a narrow place.
The position of the main body of the vacuum cleaner can be changed for convenient operation.

[0003]

However, according to the above-described conventional publicly known vacuum cleaner, since the main body of the vacuum cleaner which removes the dust by filtering the air flow containing the dust with the cloth bag is used, Is destined to decrease the suction force due to the resistance of the cloth bag when it passes through the cloth bag, and a motor with a large output is required to compensate for that resistance, which results in a larger vacuum cleaner body or loud noise. ，
The problem was that it lacked usability and convenience. Moreover, since the structure is such that dust can be sucked in only through the above-mentioned intake port, it is necessary to clean the gap where the intake port cannot pass, cleaning of high positions such as desks, walls, and ceilings.
There was a problem that it was not suitable for cleaning the inside of deep gaps. The present invention is intended to solve the above problems inherent in the conventional electric vacuum cleaner as described above.

[0004]

In order to achieve the above object, the present invention provides an intake port for sucking dust at one end, an operating rod having a handle part at the other end, and air together with the intake port. A vacuum cleaner body having a built-in cyclone-type dust collector that separates and collects inhaled dust from air by centrifugal force, and the cleaner body is positionally fixed and slidably provided on the operating rod. It is configured as an electric vacuum cleaner characterized in that The cyclone type dust collector used here is efficient because it separates air and dust by the centrifugal force generated by the swirling flow and has low noise. Therefore, it is extremely useful and convenient as a vacuum cleaner used indoors. It can be said that it is excellent. Moreover, since such a cleaner body can be mounted on the operating rod in a slidable and position-fixable manner, by fixing the cleaner body to a position close to the handle part, it can be freely used in narrow places and high places such as curtains. It can be used for, and the convenience is further improved. In addition, the cleaner body may be slidably provided on the operating rod via a holding base slidably provided on the operating rod. In this case, since the main body of the vacuum cleaner can be used separately from the holding table, the vacuum cleaner can be freely carried and the convenience of the vacuum cleaner is further improved. Also, in this case, the attachment to the operating rod becomes robust and the life can be extended. Furthermore, when the urging means for constantly urging the cleaner body toward the handle portion is provided, the cleaner body can be lightly moved along the operating rod, and the burden on the operator is reduced. To be done. As the biasing means, a spring that applies a biasing force of a substantially constant load to the cleaner body can be adopted. With this configuration,
With a simple device, it is possible to provide a device that does not fluctuate in force when the cleaner body is moved along the operating rod. In this case, by making the urging force of the urging means substantially equal to the load of the sliding body that slides on the operating rod, the force required to move the cleaner body can be almost completely eliminated. The burden on the operator is significantly reduced. Regarding the operating rod, the intake port and the intake port of the cyclone dust collector are connected to each other by a flexible and flexible intake pipe, and one end of the intake pipe is detachably connected to the intake port. You can As a result, the intake port and the cyclone dust collector can be flexibly connected. Further, by separating the connection between the intake port and the intake port, dust can be sucked in by the intake pipe itself, which is even narrower. The gap can be cleaned.
Further, as another structure relating to the operating rod, it is conceivable that the operating rod is formed in a hollow shape, and the intake port portion and the cleaner body are communicated with each other in the hollow portion of the operating rod. In this case, the intake pipe itself as described in claim 6 can be omitted, and the operating rod portion can be remarkably simplified. Furthermore, by constructing the operating rod so that it can be expanded and contracted, the problem of the space during storage can be solved. By providing a grip on the cleaner body, the operability is improved at once. Modifications relating to such a structure also belong to the scope of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION With reference to the attached drawings, an embodiment of the present invention will be described with reference to the accompanying drawings for the understanding of the present invention. 1 is an external view of a cyclone type electric vacuum cleaner according to an embodiment of the present invention (FIG. 1A is a front view thereof and FIG. 1B is a side view thereof), and FIG. (A) is a longitudinal sectional view, and (b) is an AA sectional view of (a). As shown in FIG. Is locked,
On the operating rod 3 with the handle 2 rotatably provided at the other end,
A cleaner body 4 having a cyclone type dust collector 6 (see FIG. 2) therein is slidably locked. The intake port 1 and the cleaner body 4 are connected by an expandable and bendable intake pipe 7 composed of a bellows hose and the like, and the intake pipe 7 allows the cleaner body 4 to move along the operation rod 3. It also expands and contracts.

Reference numeral 1b is a rotary brush rotatably arranged in the intake port 1, and is rotated by an electric motor or an air flow to scrape out dust inside the bristles of a carpet or the like. In addition, 6 shown in FIG.
Reference numeral 4 is a control device for controlling the cleaner body 4, and reference numeral 65 is an operation unit for operating the cleaner body 4. The intake pipe 7
Has one end connected to the intake port 1 and the other end connected to the intake port 72 of the cyclone dust collector 6. As a result, the suction port 1a of the intake port portion 1 and the inside of the cyclone dust collecting device 6 are communicated with each other, and the dust is sucked into the cyclone dust collecting device 6 from the intake port portion 1 through the intake pipe 7. The sucked air flow swirls in the dust cup 83, and the dust is separated by the centrifugal force and accumulated in the dust cup 83. The air from which dust has been separated and purified enters the exhaust pipe H through the exhaust port Ha of the exhaust pipe H,
It is sucked by the upper electric blower M and discharged from the slit S to the outside. A mesh-shaped filter F is fixed to the exhaust port Ha to capture dust that cannot be separated. In this way, the cyclone type dust collector 6 removes dust particles in the process of air flow and simply generates and passes the air flow, so that there is little loss, light weight and downsizing, and noise can be reduced. It is excellent in usability and operability, especially when it is used by moving it at hand, and because of its small size, it has excellent usability and operability. Further, one end of the intake pipe 7 is detachably connected to the intake port portion 1 by fitting by means of a taper, locking or the like, and the other end is provided with an intake port 72 (see FIG. 1) of the cyclone dust collector 6.
It is rotatably connected to (b)). Therefore, one end of the intake pipe 7 removed from the intake port 1 can be freely moved to a position to be cleaned, as shown by a broken line 7a in FIG. 1, and any position can be cleaned vertically and horizontally. As a result, it is possible to easily clean the gap at any position, the curtain, or even the desk at a high position.

In this embodiment, the cleaner body 4 is attached to a holding table 5 that slides on the operating rod 3. Lock means for fixing the holding table 5 on the operating rod 3 is provided between the operating rod 3 and the holding table 5, and the holding table 5 is held at a predetermined position on the operating rod 3. A plurality of lock hand throws are provided at arbitrary positions on the holding rod 3. For example, the concave grooves 31a and 31b on the operation rod 3 shown in FIGS. The holding table 5 is fixed on the operating rod 3 by engaging with the groove 31a or 31b. The lock lever 8 is always elastically biased by a spring (not shown) in a direction to be fitted in the groove 31a, so that the meshed state is obtained by operating the rock scraper 8 in a direction opposite to the biasing direction of the spring. Can be released. When the cleaner body 4 is moved along the operating rod 3, the lock scraper 8 is released and the grip portion 62 is moved as described above. As a result, the cleaner body 4 can be easily moved together with the holding table 5, and the lock lever 8 can be engaged and fixed to the other recess 31b. Therefore, the recesses 31a, 3
By adding 1b to an appropriate position, the cleaner body 4 can be enclosed in multiple stages. The locking means may be a method in which a shoe having a frictional force is locked to the holding table 5 and the outer circumference of the operating rod 3 is tightened. In this case, when moving the cleaner body 4, the shoes are loosened and moved. According to this, the cleaner main body 4 can be fixed to a desired position without steps without the concave portions 31a and 31b. By moving the cleaner body 4 to the predetermined position in this way, when cleaning the floor surface, the cleaner body 4 is fixed to the intake port 1 side so that the center of gravity is on the floor side, and as shown in FIG. , Or handle 2 when cleaning deep places
By moving to the side and lengthening the distance between the cleaner body 4 and the intake port 1, it is possible to use efficiently and improve usability and convenience. Further, at this time, by rotating the handle 2 to a position where it does not come into contact with the floor, cleaning can be performed efficiently even in a narrower space.
Particularly, by attaching the cleaner body 4 provided with the small and light cyclone type dust collecting device 6 slidably, even if the cleaner body 4 is moved to the handle 2 side, the load burden is reduced and comfortable usability is obtained.

Next, a structure for attaching / detaching the cleaner body 4 to / from the holder 5 will be described. In FIG. 2, a convex portion 6a protruding from the lower end of the cleaner body 4 is engaged with a concave portion 5a provided at the lower end of the holding table 5, and a holding lever 9 rotatably provided at the upper end portion of the cleaner body 4 is The vacuum cleaner body 4 is always elastically urged downward and engages with the convex portion 5b provided on the upper end of the holding table 5, so that the cleaner main body 4 has the concave portion 5a and the convex portion 6a at the lower end portion of the holding table 5. The convex portion 5b and the holding lever 9 mesh with each other at the upper end portion and are fixed to the holding table 5. In this way, the cleaner body 4 and the holding table 5 slide together on the operation rod 3 in the axial direction. In addition, the holding lever 9 is released to remove the cleaner body 4 from the holding table 5, and one end of the intake pipe 7 is removed from the intake port 1 to separate it from the operating rod 3 and the intake port 1 The main body 4 alone can be used as an electric vacuum cleaner. In other words, it can be used as a handy type for cleaning high places and inside automobiles. On the other hand, the holding table 5 is moved upward by a belt-shaped spring 10.
Here, it is always biased in the direction of the handle 2. That is, the spring 10 is the cleaner body 4, here the holding table 5
, And the other end is wound around the rotating wheel portion 11 to urge the cleaner body 4 toward the handle 2. The spring 10 itself is covered with a cover 31c that constitutes the outer shell of the operating rod 3, and prevents the spring 10 from being exposed and being touched or damaged by a human finger, and the appearance is maintained.

The spring 10 is a constant load spring and applies a constant load. The urging force of the spring 10 is set to be approximately equal to or slightly smaller than the weight of the suspended object including the cleaner body 4 and the holding table 5. As a result, the cleaner body 4 can be automatically moved in the direction of the handle 2 by the urging force of the spring 10 by removing the lock lever 8 and inclining the operating rod 3, so that the cleaner body 4 can be moved. Operability and convenience are improved without the need for a person to pull up. Also,
When moving the cleaner body 4 in the direction opposite to the handle 2, simply by opening the lock lever 8 and standing the rod 3 vertically, the suspended body such as the cleaner body 4 is moved in the direction opposite to the handle 2 by its own weight. It can be moved to improve operability and convenience. Moreover, spring 1
Since it moves with a constant load that is the difference between the urging force due to 0 and the load of the suspended body such as the cleaner body 4, the moving speed of the cleaner body 4 does not change depending on the inclination of the operating rod 3 During the moving period of the machine body 4, it smoothly moves at a constant speed and does not cause a sense of crisis or discomfort. Also, when the cleaner body 4 is moved by hand, the load of the cleaner body 4 is offset by the spring 10, so that the force for moving the cleaner body 4 is small and the operability is improved. Further, in order to fix the movement of the cleaner body 4 along the operation rod 3, the spring 10 may be held and fixed so as to stop the movement of the spring 10. As a result, the movement of the spring 10 is blocked, so that the cleaner body 4 can be fixed. As shown in FIG. 2A, the operating rod 3 may also have a double structure of a hollow moving operating rod 31 and a fixed operating rod 32 slidably fitted in the hollow portion of the moving operating rod 31. Good. This makes the operating rod 3
Is configured to be flexible. FIG. 2A is a state diagram in which the operating rod 3 is extended, and the moving operating rod 31 shown by a broken line shows a state in which the moving operating rod 3 is stored on the intake port 1 side. The sliding members 33a, 3 are provided between the outer circumference of the fixed operation rod 32 and the movable operation rod 31.
It is configured so that it can smoothly slide through 3b.
In addition, the fixation of the moving operation rod 31 and the fixed operation rod 32 is
A locking means (not shown) may be provided at a predetermined position so that the locking device can lock at a predetermined length. As a result, the handle 2 can be used with the handle 2 set in an appropriate position, or the vacuum cleaner can be housed and stored with a reduced overall length.

One of the cleaner body 4 and the holding table 5 is slidably held on the outer circumference of the moving operation rod 31 and the other on the outer circumference of the fixed operating rod 32 by a sliding member 12 such as a bearing (see FIG. 2).
(See (b)), the lower end of the fixed operating rod 32 is detachably locked by fitting and fixing the second connecting pipe 14 of the intake port 1 with a taper, while the intake port 1 has the first connection. The pipe 13 and the spherical sliding portion 13a are connected so as to be rotatable in the XY directions.
The connecting pipe 13 of is connected to the second connecting pipe 14 by the rotating shaft 14a so as to be rotatable in the PQ direction (see FIG. 1 (a)).
Is preferably configured to be freely rotatable with respect to the operating rod 3 in the XY and PQ directions. The connection part of the intake pipe 7 to the intake port 1 may be any part as long as it communicates with the intake port 1a of the intake port 1, but as described above,
Since the operating rod 3 rotates in the X-Y and P-Q directions, it is desirable to connect the intake pipe 7 to the second connecting pipe 14 that is movable integrally with the operating rod 3. As a result, the intake pipe 7 is only expanded and contracted by the movement of the cleaner 4, and fatigue and damage due to twisting and bending are reduced. In the example shown in FIG. 2, the second connecting pipe 14 is connected to the first connecting pipe 13, but in this case, when the operating rod 3 moves in the X-Y direction, the first connecting pipe 14 is connected. Since it swings integrally with the pipe 13, fatigue and damage due to twisting and bending in this direction are reduced.

Further, by removing the air intake port 1, the tip of the operating rod 3 can be inserted into a narrower gap and air can be sucked from the opening of the tip for cleaning. Furthermore, intake port 1
It is possible to efficiently clean a narrow gap by removing the above and connecting various suction ports to the tip of the operating rod 3. Although various embodiments and examples of the present invention have been described above, what has been shown so far is an exemplification of the configuration of the invention, and the scope of the present invention is not limited to this, and FIG. As shown, a plurality of operating rods 3a and 3b are provided, and a configuration in which the holding table 5 slides on the plurality of operating rods 3a and 3b is added with various modifications without departing from the gist of the invention. It can be carried out.
