However, according to the conventional vacuum cleaner, the main body of the vacuum cleaner is used to remove dust by filtering the air flow containing dust through a cloth bag. There is a destiny that power is reduced, and an electric motor with a large output is required to compensate for the resistance, and therefore the problem is that the vacuum cleaner main body becomes large or the noise becomes loud and the usability and convenience are lacking. Had.
In addition, the dust can only be sucked in from the air intake, so that the air intake cannot pass through, the desk, wall, ceiling, etc. The problem was that it was not suitable for cleaning.
The present invention aims to solve the above-mentioned problems inherent in the conventional vacuum cleaner as described above.

In order to achieve the above-mentioned object, the present invention separates the dust sucked from the suction port together with the air by the centrifugal force with the operation port having the suction port sucking dust at one end and the handle at the other end.

Furthermore, when the urging means for constantly urging the vacuum cleaner main body in the direction of the handle is provided, the vacuum cleaner main body can be moved lightly along the operation rod, reducing the burden on the operator. Is done. As the biasing means, a spring that applies a biasing force with a substantially constant load to the cleaner body can be employed. By comprising in this way, an apparatus without the fluctuation | variation of force when moving a cleaner main body along an operating rod with a simple apparatus can be provided. In this case, the force required to move the cleaner body can be almost completely eliminated by making the urging force by the urging means substantially the same as the load of the sliding body sliding on the operating rod. , The burden on the operator is significantly reduced.
Further, the intake port and the intake port of the cyclone type dust collector are connected by an extendable and bendable intake pipe, one end of the intake pipe is detachably connected to the intake port, and the intake port is connected to the intake port. It can be arranged on the side of the cleaner body. As a result, the intake port and the cyclone dust collector can be connected flexibly, and by separating the connection from the intake port of the intake pipe, dust can be sucked in by the intake pipe itself. Narrow gaps can be cleaned.

An embodiment of the present invention will be described with reference to the accompanying drawings, and an embodiment of the present invention will be described for understanding of the present invention.
FIG. 1 is an external view of a cyclonic vacuum cleaner according to an embodiment of the present invention (FIG. 1A is a front view thereof, 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. 1, a cyclone dust collector 6 (see FIG. 2) is installed inside an operating rod 3 having an inlet 1 locked at one end and a handle 2 rotatably provided at the other end. The vacuum cleaner main body 4 provided in is slidably locked.
The intake port 1 and the cleaner body 4 are connected by an intake pipe 7 formed of a bellows hose and the like so as to be stretchable and bendable. The intake pipe 7 moves along the operation rod 3 of the cleaner body 4. It expands and contracts with it.

Reference numeral 1b denotes a rotating brush that is rotatably arranged in the air inlet 1 and rotates by an electric motor or an air flow to scrape dust inside hair such as a carpet. Also, 64 shown in FIG. 2 is a control device that controls the cleaner body 4, and 65 is an operation unit that operates the operation of the cleaner body 4.
One end of the intake pipe 7 is connected to the intake port 1, and the other end is connected to the intake port 72 of the cyclone dust collector 6. As a result, the suction port 1 a of the intake port 1 communicates with the inside of the cyclone dust collector 6, and dust is sucked from the intake port 1 through the intake pipe 7 into the cyclone dust collector 6. The sucked air flow swirls in the dust cup 83, and dust is separated by centrifugal force and accumulated in the dust cup 83. Dust separated and purified air enters the exhaust pipe H through the exhaust port Ha of the exhaust pipe H, is sucked into the upper electric blower M, and is discharged to the outside through the slit S. Further, a mesh-like filter F is fixed to the exhaust port Ha, and traps dust that could not be separated.
In this way, the cyclone type dust collector 6 removes dust in the course of air flow and simply generates and passes the air flow, so there is little loss, it can be reduced in size and weight, and noise can be reduced. There are few, and it is excellent in usability and operability, and it is excellent in usability and operability due to its light weight and small size especially when moved to hand.
In addition, one end of the intake pipe 7 is detachably connected to the intake port 1 by fitting with a taper or locking, and the other end is an intake port 72 provided in the cyclone type dust collector 6 (FIG. 1B). )). Accordingly, one end of the intake pipe 7 removed from the intake port 1 can be freely moved to a position to be cleaned as indicated by a broken line 7a in FIG. As a result, it is possible to easily clean a gap at an arbitrary position, a curtain, or a desk at a higher position.

In the present embodiment, the cleaner body 4 is engaged with a holding base 5 that slides on the operation rod 3. Between the operation rod 3 and the holding table 5, there is provided locking means for fixing the holding table 5 on the operation rod 3, and the holding table 5 is held at a predetermined position on the operation rod 3.
A plurality of the lock hand throws are provided at arbitrary positions on the operation rod 3. For example, the concave grooves 31a and 31b on the operating rod 3 shown in FIGS. 1 and 2 are a part of the locking means, and the lock lever 8 provided on the holding base 5 so as to be rotatable around the pin 8b is the concave groove. The holding stand 5 is fixed on the operating rod 3 by meshing with 31a or 31b. Since the lock lever 8 is always elastically biased by a spring (not shown) in a direction in which the lock lever 8 is fitted into the groove 31a, the meshing state operates the lock lever 8 in a direction opposite to the spring biasing direction. Can be canceled.
When the cleaner body 4 is moved along the operation rod 3, the lock lever 8 is released as described above, and the gripper 62 is moved. Thereby, the cleaner main body 4 can be easily moved together with the holding base 5, and can be fixed by engaging the lock lever 8 with the other recess 31b. Therefore, the vacuum cleaner body 4 can be enclosed in a multi-stage position by adding the recesses 31a and 31b to appropriate positions. This locking means may be a system in which a shoe having frictional force is engaged with the holding base 5 and the outer periphery of the operating rod 3 is tightened. In this case, when the cleaner body 4 is moved, the shoe is loosened and moved. According to this, the vacuum cleaner main body 4 can be fixed at a desired position in a stepless manner without requiring the recesses 31a and 31b.
By moving the cleaner body 4 to a predetermined position in this way, when cleaning the floor surface, the cleaner body 4 is fixed to the intake port 1 side, the center of gravity is on the floor side, and as shown in FIG. Or, when cleaning a deep place, it can be used efficiently by moving to the handle portion 2 side to lengthen the space between the vacuum cleaner main body 4 and the intake port portion 1 and improve usability and convenience.
At this time, the handle portion 2 is rotated to a position where it does not come into contact with the floor, so that it can be efficiently cleaned even in a narrow space. In particular, by attaching the vacuum cleaner main body 4 having a small and lightweight cyclone type dust collecting device 6 so as to be slidable, the load is reduced even if the cleaner body 4 is moved to the handle portion 2 side, and a comfortable usability can be obtained. .

Next, a structure for attaching / detaching the cleaner body 4 to / from the holding base 5 will be described. In FIG. 2, a convex portion 6 a protruding from the lower end of the cleaner body 4 is engaged with a concave portion 5 a provided at the lower end of the holding base 5, and a holding lever 9 provided rotatably at the upper end portion of the cleaner body 4 is The vacuum cleaner body 4 is always elastically biased downward and meshes with the convex portion 5b provided at the upper end of the holding base 5, whereby the vacuum cleaner main body 4 has the concave portion 5a and the convex portion 6a at the lower end thereof. Further, the convex portion 5b and the holding lever 9 are engaged with each other at the upper end portion and fixed to the holding base 5. Thus, the cleaner main body 4 and the holding base 5 slide together in the axial direction on the operation rod 3.
Further, by releasing the holding lever 9 to remove the cleaner body 4 from the holding stand 5 and removing one end of the intake pipe 7 from the intake port 1, the vacuum cleaner is separated from the operation rod 3 and the intake port 1. The main body 4 alone can be used as a vacuum cleaner. In other words, it can be used as a handy type for cleaning high places or automobiles.
On the other hand, the holding base 5 is always urged upward by a belt-like spring 10, in this case, in the direction of the handle portion 2. That is, one spring 10 is locked to the cleaner body 4, here the holding stand 5, and the other end is wound around the rotating wheel portion 11, and urges the cleaner body 4 toward the handle portion 2. The spring 10 itself is covered with a cover 31c that constitutes the outer shell of the operation rod 3 to prevent the spring 10 from being exposed and touching or damaging a person's finger and maintaining aesthetics.

The spring 10 is a constant load spring and biases a constant load. The urging force of the spring 10 is set to a value approximately equal to or slightly smaller than the weight of the suspended body including the cleaner body 4 and the holding stand 5. Accordingly, the cleaner body 4 can be automatically moved in the direction of the handle portion 2 by the urging force of the spring 10 by removing the lock lever 8 and tilting the operating rod 3. There is no need for a person to lift the operability and convenience.
Further, when moving the cleaner body 4 in the direction opposite to the handle 2, the lock lever 8 is opened and the reed rod 3 is set up vertically so that the counter handle is lifted by the weight of the suspended body such as the cleaner body 4. Operation in the direction of section 2 is improved and operability is improved. In addition, the moving speed of the cleaner main body 4 varies depending on the degree of inclination of the operation rod 3 because it moves with a constant load corresponding to the difference between the biasing force of the spring 10 and the load of the suspended body such as the cleaner main body 4. In addition, during the movement period of the cleaner body 4, it moves smoothly at a constant speed and does not cause a sense of crisis or discomfort. Further, when the cleaner body 4 is moved by hand, the load of the cleaner body 4 is canceled 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 restrain the movement of the spring 10. Thereby, since the movement of the spring 10 is prevented, the cleaner body 4 can be fixed.
Further, as shown in FIG. 2A, the operation rod 3 may have a double structure including a hollow movement operation rod 31 and a fixed operation rod 32 slidably fitted in the hollow portion of the movement operation rod 31. Good. Thereby, the operation rod 3 is configured to be extendable. FIG. 2A is a state diagram in which the operating rod 3 is extended, and a moving operating rod 31 indicated by a broken line shows a state in which the moving operating rod 31 is stored on the intake port 1 side. The outer periphery of the fixed operating rod 32 and the moving operating rod 31 are configured to be able to slide smoothly via the sliding members 33a and 33b. Further, the moving operation rod 31 and the fixing operation rod 32 may be fixed by providing a lock means (not shown) at a predetermined position and locking it at a predetermined length. Thereby, it can be used in a state where the handle portion 2 is set at an appropriate position, and the electric vacuum cleaner can be stored and stored with a reduced overall length.

The vacuum cleaner body 4 and the holding stand 5 are slidably held on the outer periphery of the moving operation rod 31 and on the outer periphery of the fixed operation rod 32 by the sliding member 12 such as a bearing (see FIG. 2B). The lower end of the fixing operation rod 32 is detachably locked by being fitted and fixed to the second connection pipe 14 of the intake port portion 1 with a taper, while the intake port portion 1 is spherically connected to the first connection tube 13. The sliding portion 13a is rotatably connected in the XY direction (see FIG. 1B), and the first connecting pipe 13 is connected to the second connecting pipe 14 and the rotating shaft 14a in the PQ direction (FIG. 1A). It is preferable that the intake port portion 1 is configured to be freely rotatable in the XY and PQ directions with respect to the operation rod 3.
The connection portion of the intake pipe 7 to the intake port portion 1 may be any portion as long as it is a portion communicating with the intake port 1a of the intake port portion 1. However, as described above, the intake port portion 1 and the operating rod 3 are XY and Since it rotates in the PQ direction, it is desirable to connect the intake pipe 7 to the second connection pipe 14 that can move integrally with the operation rod 3. Thereby, the intake pipe 7 is only expanded and contracted by the movement of the cleaner 4, and fatigue and breakage due to twisting and bending are reduced. In the example shown in FIG. 2, the second connection pipe 14 is connected to the first connection pipe 13, but in this case, when the operating rod 3 is movable in the XY direction, the first connection pipe 14 is connected. Since it swings integrally with the tube 13, fatigue and breakage due to twisting and bending in this direction are reduced.

FIG. 4 is a longitudinal sectional view showing an intake passage portion of the cleaner body 4 in the electric vacuum cleaner according to the embodiment of the present invention in which the intake passage 71 is provided inside the operation rod 3. Other configurations are the same as those of the embodiment shown in FIGS.
In this case, the operating rod 3 is composed of a moving operating rod 31 and a fixed operating rod 32 as in the above-described embodiment, and the moving operating rod 31 slides in the fixed operating rod 32 and expands and contracts. Here, the fixed operating rod 32 is formed hollow and forms the intake passage 71.
An outward opening 35 is formed in the vicinity of the upper end of the fixed operation rod 32 and communicates with a space 36 formed in the holding table 5. Reference numerals 361 and 362 denote sealing materials provided on the holding table 5 in order to configure the space 36 in a closed chamber state. A space 36 provided in the holding table 5 communicates with the cyclone type dust collector 6 through an intake port 66 as shown in the figure. Therefore, by attaching the intake port 1 to the lower end of the intake passage 71 of the fixed operation rod 32, the intake port 1a opened to the floor surface of the intake port 1 and the intake passage 71 in the operation rod 3 communicate with each other. Thus, an intake path between the cyclone type dust collector 6 and the intake port 1 is formed.
Since the space 36 is formed to be long in the vertical direction of the holding base 5, from the state where the cleaner body 4 is located near the air inlet 1 as shown in FIG. 4A, as shown in FIG. Even if it moves to the uppermost position, the fixed operation rod 32 always communicates with the space 36 through the opening 35, so that the electric blower M is driven wherever the cleaner body 4 is located. Then, dust on the floor is sucked together with air from the suction port 1a of the suction port 1 and passes through the suction path 71 of the fixed operating rod 32, and is sucked into the cyclone type dust collector 6 from the suction port 66 through the space 36 from the opening 35. Is done. The sucked air flow including the dust flowing into the cyclone type dust collector 6 turns to separate the dust, and the purified air flow enters the exhaust pipe H through the exhaust port Ha of the exhaust pipe H, The air is sucked by the electric blower M and discharged from the slit S to the outside. The separated dust is accumulated in the dust cup 63. Further, the point that a mesh-like filter is attached to the exhaust port Ha is similar to the embodiment, and dust that cannot be separated is captured.
In the state of FIG. 4 (b), since the length L between the air inlet 1 and the vacuum cleaner body 4 becomes long, the narrow gap can be inserted and cleaned without interfering with the space between the vacuum cleaner main bodies 4. Can do.
Further, by removing the air inlet 1, the tip of the operating rod 3 can be inserted into a narrower gap, and air can be sucked and cleaned from the opening at the tip. Further, by removing the air inlet 1 and connecting various inlets to the tip of the operating rod 3, it is possible to efficiently clean the narrow gap.
Although various embodiments and examples of the present invention have been described above, what has been described so far is an example of the configuration of the invention, and the scope of the present invention is not limited to this, and FIG. As shown in the drawing, a plurality of operation rods 3a and 3b are provided, and the holder 5 slides on the plurality of operation rods 3a and 3b, and various modifications are made without departing from the gist of the invention. Can be implemented.
