The hose skin 26 is integrally molded in a state where the hose skin 26 is inserted concentrically along the axial direction. The hose skin 26 is formed of a flexible synthetic resin such as soft polyvinyl chloride, and hermetically covers the periphery of the reinforcing material 22 to form the suction air passage 27 inside. Therefore, the surface of the hose skin 26 has a substantially bellows shape due to the rigidity of the reinforcing material 22. Furthermore, this hose skin 26 is a reinforcement material.
Together with 22, it forms a slender cylindrical hose body 28 that is bendable and capable of contracting and maintaining its shape retention.

Further, in each void portion 25 of the reinforcing member 22 inside the hose skin 26, a power signal line 31 as an electric wire is provided.
However, in the state of being inserted through each of these voids 25, the hose skin 26 is brought into contact with and bonded or welded to the inner peripheral surface of the hose skin 26 in the axial direction of the hose skin 26. Therefore, the power signal line 31 is provided between the straight line portions 24 of the reinforcing member 22 without interposing any of the curved portion 23 and the straight line portion 24 of the reinforcing member 22 with the inner peripheral surface of the hose skin 26. Is disposed in the void portion 25 in.

Here, the power supply signal line 31 is a pair of leads which are transmission lines as conductors each surface of which is covered with a coating 32 formed of a synthetic resin such as polypropylene or hard polyvinyl chloride. It is composed of line 33. These lead wires 33 are insulated from each other by the coating 32 of each other. One of the pair of lead wires 33 serves as a power supply line that supplies electric power to the electric motor 54 that rotationally drives the rotary brush 53 of the floor brush 52. The other of the pair of lead wires 33 is the setting button of the manual operation unit 43.
It becomes a signal line for transmitting a control signal by turning on and off 45.

On the other hand, the base end which is one end of the hose 21 is connected to a substantially cylindrical connecting pipe 41 which is detachably inserted into the main body suction port 17 of the suction portion 18 of the cleaner main body 11. . The base end of a substantially cylindrical rotary tube 42 is connected to the other end of the hose 21, which is the other end. This rotating tube
The tip of 42 is a hand operation part that will be a grip when cleaning
It is connected to the base end of 43 so as to be rotatable in the circumferential direction.

A suction air passage (not shown) that is airtightly communicated with the suction air passage 27 of the hose 21 is formed inside the hand operation portion 43. Further, the hand operation unit 43 is formed in an elongated cylindrical shape with an intermediate portion bent in a substantially V shape for improving the usability. Furthermore, this hand operation part

A setting button 45 is provided as various operating means for setting and operating the drive state of the electric motor 54 that rotationally drives the rotary brush 53.

An extension pipe 51, which is an elongate and contractible elongated cylindrical connecting pipe for extending the tip of the hand operation part 43, is detachably connected to the tip of the hand operation part 43. Further, a base end of a floor brush 52 as a substantially convex suction port body having a suction port 55 opened at a lower end surface facing the floor surface is detachably connected to the tip of the extension pipe 51. .

A rotary brush 53 is rotatably supported at a position facing the suction port 55 of the floor brush 52, as a rotary cleaning member for scraping out dust that has entered the carpet or the like to be cleaned by rotation. Installed. The rotating brush 53 rotates along the traveling direction of the floor brush 52. Further, inside the floor brush 52, an electric motor 54 that rotationally drives the rotary brush 53 is housed. This electric motor 54
It is electrically connected to the lead wires 33 of the hose 21, and the rotation drive is controlled by the power supply and signals supplied from these lead wires 33.

Next, the cleaning operation of the first embodiment will be described.

First, the dust collecting cup 14 is placed and held on the front side of the case body 12.

After that, the lid 15 is rotated so that the lower surface is pressed against and covers the upper surface of the case body 12 and the upper surface of the dust collecting cup 14, and the exhaust side of the dust collecting cup 14 and the suction side of the electric blower 13 are rotated. And communicate with each other in a substantially airtight manner.

A hose is attached to the main body suction port 17 of the suction section 18.
The base end of the connecting pipe 41 of 21 is connected, and the floor brush 52 or the extension pipe 51 to which the floor brush 52 is connected to the tip is connected to the tip of the hand operation part 43 of the hose 21 to enter the cleaning standby state. .

In this state, the predetermined setting button 45 of the hand operation section 43 of the hose 21 is operated to drive the electric blower 13 and the electric motor 54 as required, and the hand operation section 43 is pushed and pulled. , Clean the floor brush 52 by running it on the floor.

Then, dust is sucked together with air from the suction port 55 of the floor brush 52, and the sucked dust is sequentially passed through the extension pipe 51 and the hose 21 from the main body suction port 17 of the suction section 18 to the dust collecting cup 14. Is sucked into the inside of the dust collecting cup 14 and swirls in a spiral shape inside the dust collecting cup 14.

At this time, the dust sucked into the dust collecting cup 14 falls along the inner surface of the dust collecting cup 14 due to the centrifugal force of the swirling air of the air swirling in the dust collecting cup 14 and its own weight. Are collected.

Further, the air swirled inside the dust collecting cup 14 is sucked from the center of the vortex of the dust collecting cup 14 through the inside of the lid 15 to the suction side of the electric blower 13, and the electric blower is blown. The air is exhausted by 13 and is exhausted to the outside from the exhaust port 16 of the case body 12.

Next, the operation of the first embodiment will be described.

When the hose 21 is discarded due to the breakage of some of the lead wires 33 in the hose 21 or the hose skin 26, the reinforcement member 22 of the hose 21 must be discarded. A knife or the like is inserted into the void 25 of the hose 21 and a cut is made in the hose skin 26 along the longitudinal direction of the hose 21.

Next, a part of the power supply signal line 31 attached to the void portion 25 of the reinforcing material 22 in the hose 21 is pulled out from this cut, and the power supply signal line 31 is connected to the hose 21.
The power signal line 31 is pulled to the hose 21
Can be removed from.

As described above, according to the first embodiment, the voids 25 communicating with each other between the straight portions 24 of the reinforcing member 22 of the hose 21 are provided in the longitudinal direction which is the axial direction of the hose 21. By arranging the power supply signal line 31 along,
The power signal line 31 can be arranged on the inner surface of the hose skin 26 without interposing either the curved portion 23 or the straight portion 24 of the reinforcing member 22.

For this reason, the hose skin 26 is cut and cut with a knife or the like across each of the voids 25 between the straight portions 24 of the reinforcing member 22, so that the hose skin is cut.
The power supply signal line 31 can be pulled out from the inside of the hose skin 26 without being disturbed by the reinforcing material 22 in the 26. Therefore, since the power supply signal line 31 which is generally made of a relatively expensive copper wire or the like can be easily disassembled from the hose skin 26 of the hose 21 and the reinforcing material 22, the power supply signal line 31 can be easily recycled. it can.

Further, since the reinforcing material 22 which is provided integrally with the hose skin 26 and prevents the hose skin 26 from being crushed or bent is molded of synthetic resin, the power supply signal line 31 is formed as described above.
When the hose 21 is pulled out, only the synthetic resin remains in the hose 21, and it becomes easy to discard the hose 21 from which the power signal line 31 is separated. Therefore, by simply separating the power signal line 31 from the hose 21, the hose 21 of the vacuum cleaner, which is generally not easy to recycle, can be easily recycled.
The environmental load due to can be reduced.

Further, since the power signal line 31 is linearly arranged on the inner surface of the hose skin 26 along the longitudinal direction of the hose 21, the power signal line is spirally formed on the inner surface of the hose skin as in the conventional case. Compared to a hose that is wound and arranged in the longitudinal direction, the power signal line 31 does not need to be spirally wound on the inner surface of the hose skin 26.
Can be shorter than the length of the reinforcing member 22. Therefore, the amount of the lead wire 33 formed of a relatively expensive copper wire or the like can be reduced by about 1/10, and the manufacturing cost of the hose 21 can be reduced.

Next, the configuration of the second embodiment of the present invention will be described with reference to FIG.

The hose 21 shown in FIG. 3 is basically the same as the hose 21 shown in FIGS. 1 and 2, except that the outer surface of the rigid synthetic resin reinforcement 22 wound in a spiral shape is A plurality of concave groove portions 61 having a concave arc shape in cross section are provided, and the concave groove portions 61 are gradually shifted in a spiral shape and wound to communicate with each other to form the void portion 25.

The voids 25 formed by the recessed groove portions 61 are spirally wound in the same direction as the winding direction of the reinforcing material 22 at intervals wider than the winding pitch of the reinforcing material 22. Has been done. Further, a power supply signal line 31 is disposed between the space 25 and the hose skin 26, which are formed by the recessed groove portions 61, and the power supply signal line 31 extends in the winding direction of the reinforcing member 22. Is wound in a spiral in the direction equal to
Are arranged substantially along the longitudinal direction of.

For this reason, in the hose 21 shown in FIG. 3, the hose skin 26 is cut across the recessed groove portions 61 of the reinforcement member 22 which are in communication with each other, so that the reinforcement member 22 in the hose skin 26 is obstructed. Since it is possible to pull out the power signal line 31 from the inside of the hose skin 26 without disconnecting it,
The same effects as those of the hose 21 shown in FIGS. 1 and 2 can be obtained.

Further, each concave groove portion 61 of the reinforcing member 22 of the hose 21.
Is provided at a position where the reinforcing member 22 is spirally wound along the winding direction of the reinforcing member 22, therefore, by wiring the power signal line 31 in the void portion 25 formed by each of the concave groove portions 61, With the power supply signal line 31 wired, the hose 21 can be expanded and contracted in the longitudinal direction due to the flexibility of the hose skin 26, and the hose 21 can be further curved.

Accordingly, the power supply signal line 31 can be easily separated from the hose 21, and the problem that the environmental load due to the hose 21 can be reduced can be solved while the power supply signal line 31 is being solved.
It is possible to further prevent breakage of the power supply signal line 31 when the hose 21 is extended or curved in the longitudinal direction without slackening and wiring, so that the usability of the hose 21 can be further improved.

In addition, each groove 61 of the reinforcement 22 of the hose 21
, Since it is spirally wound in the same direction as the winding direction of the reinforcing member 22, by wiring the power supply signal line 31 in the void portion 25 formed by these recessed groove portions 61, Reinforcement material 22 generated when the hose 21 is stretched in the longitudinal direction
Since the power supply signal line 31 extends in accordance with the extension of the hose 21 in the longitudinal direction, breakage of the power supply signal line 31 when the hose 21 is extended in the longitudinal direction can be prevented more reliably.

Since the voids 25 formed by the concave groove portions 61 of the reinforcing member 22 are spirally wound at intervals wider than the winding pitch of the reinforcing member 22 of the hose 21, the voids are formed. twenty five
The length of the power supply signal line 31 can be shortened while solving the problem that the hose 21 can be prevented from being broken by the power supply signal line 31 that is wired to the.

By wiring the power signal line 31 in the space 25 of the reinforcing member 22 of the hose 21, the power signal line 31 is arranged between the back surface of the hose skin 26 and the front surface of the reinforcing member 22. Therefore, it is possible to more reliably prevent the power supply signal line 31 from projecting or being exposed to the suction air passage 27 formed inside the hose skin 26, so that when the dust is sucked by the hose 21, the clogging of dust is caused. Can be prevented more reliably.

In the above first and second embodiments, the reinforcing material 22 is made of a hard synthetic resin.
22 may be formed of metal such as hard steel wire. By constructing the reinforcing material 22 with a single hard steel wire or the like, it becomes necessary to separate the reinforcing material 22 from the hose skin 26 when recycling the hose 21, but a relatively expensive copper wire is used. Since the power supply signal line 31 configured as described above can be easily separated, environmental load can be reduced.

Next, the configuration of the third embodiment of the present invention will be described with reference to FIG.

The hose 21 shown in FIG. 4 is basically the same as the hose 21 shown in FIGS. 1 and 2, but the reinforcing material 22 is provided by the annular reinforcing body 71 as a plurality of annular annular bodies. The hose skin 26 is reinforced by mounting the plurality of annular reinforcing bodies 71 in the hose skin 26 at equal intervals in the longitudinal direction. In addition, this reinforcement 22
Each of the annular reinforcing bodies 71 is formed in a ring shape with a synthetic resin such as hard polyvinyl chloride.

Further, at the peripheral edge of each annular reinforcing body 71 of the reinforcing member 22, there is provided an electric wire insertion hole 72 as a communication hole through which the power signal line 31 can be inserted, along the axial direction of each annular reinforcing body 71. Has been drilled. Further, in each of these annular reinforcing bodies 71, the peripheral edge on the side where the electric wire insertion hole 72 is opened is set so that the width dimension in the radial direction gradually becomes larger than the peripheral edge on the side facing the electric wire insertion hole 72. The outer peripheral edges of these annular reinforcing bodies 71 are eccentric with respect to the inner peripheral edge.

Each of the annular reinforcing bodies 71 has the wire insertion hole 72 of the annular reinforcing body 71 communicated with each other in the longitudinal direction of the hose skin 26.
The hose skin 26 and the hose skin 26 are aligned at equal intervals and are aligned in the radial direction of the hose skin 26.
The power supply signal line 31 is installed in the inside of the annular reinforcing body 71 and extends over the electric wire insertion hole 72 of each of the annular reinforcing bodies 71.

Therefore, in the hose 21 shown in FIG. 4, the hose skin 26 between the annular reinforcing members 71 of the reinforcing member 22 is cut and led out from the wire insertion hole 72 of each annular reinforcing member 71 of the reinforcing member 22. By pulling the power signal line 31, this reinforcement material
Since the power supply signal line 31 can be pulled out from the wire insertion hole 72 of each annular reinforcing body 71 without being disturbed by each annular reinforcing body 71 of 22, the same operation as that of the hose 21 shown in FIGS. 1 and 2 is performed. It is possible to exert an effect.

Further, the power supply signal line 31 is inserted into the wire insertion hole 72 of each annular reinforcing body 71 of the reinforcing member 22 and the power supply signal line 31 is inserted.
By wiring to the inner surface of the hose skin 26, it is possible to more reliably prevent the power supply signal line 31 from protruding or being exposed to the suction air passage 27 formed inside the hose skin 26. While the power signal line 31 can be easily separated, and the problem that the hose 21 can reduce the environmental load can be solved, it is possible to more reliably prevent clogging of dust when the hose 21 sucks dust.

Further, the power supply signal lines 31 are not adhered to the respective annular reinforcing bodies 71 of the reinforcing member 22 and the annular reinforcing bodies 71 are not bonded.
Since the power supply signal line 31 is simply inserted through the wire insertion hole 72, the reinforcing body 22 and the power supply signal line 31 are configured separately.
Therefore, the power supply signal line 31 can be more easily pulled out from the electric wire insertion hole 72 of each of the annular reinforcing bodies 71, so that the power supply signal line 31 can be separated from the hose 21 more easily.

Further, the peripheral edge of each annular reinforcing body 71 of the reinforcing member 22 on the side facing the electric wire insertion hole 72 is
Since the width of 72 is gradually narrowed from the peripheral edge on the opened side, the suction air inside the hose skin 26 by each of these annular reinforcements 71 is ensured while ensuring the diameter dimension of the wire insertion hole 72 of each of these annular reinforcements 71. The cross-sectional area of the passage 27 can be secured more.

In the third embodiment, the reinforcing material is used.
The inner diameter of the wire insertion hole 72 of each annular reinforcing member 71 of
Although the outer diameter of 31 is substantially matched, each of these wire insertion holes 72 is formed into an elliptical shape or an elongated hole shape that is widened in the width direction of each annular reinforcing body 71, or each of these wire insertion holes 72. By making the inner diameter of the power signal line 31 larger than the outer diameter of the power signal line 31, the power signal line 31 can freely move inside these wire insertion holes 72, so that the power signal line 31 generated when the hose 21 is bent. Breaking can be prevented more.

Further, each annular reinforcing body 71 of the reinforcing member 22 of the hose 21 can be made of metal such as hard steel wire other than synthetic resin.

In each of the above embodiments, the hose skin
Although the hose 21 having the reinforcing material 22 attached to the inner surface of 26 has been described, the inner surface of each of the hose skin 26 and the reinforcing material 22 should be covered with a covering material (not shown) made of a flexible synthetic resin. As a result, the step formed by the hose skin 26 and the reinforcing material 22 can be reduced, so that the clogging of dust by the suction air passage 27 of the hose 21 can be further prevented, and the air passage resistance by the suction air passage 27 can be reduced. it can.

Further, the canister type vacuum cleaner of the cyclone type having the dust collecting cup 14 for separating the sucked dust from the air by the centrifugal force and the own weight of the dust has been described. It may be an upright type or a handy type as long as it uses the wired hose 21, and further, an electric vacuum cleaner that captures dust by filtration using a dust collection bag, a commercial AC power supply, An electric vacuum cleaner driven by a dry battery can be used, and an electric device other than the electric vacuum cleaner can be used.
