Description

[Detailed Description of the Invention] This invention relates to a hose storage device for a vacuum cleaner.

Conventionally, there are vacuum cleaners equipped with long hoses with a length of 8 m or more, but as described in Japanese Patent Application Laid-open No. 127473/1983, for example, the storage of the long hose is done using a rotating hose inside the vacuum cleaner body. There is one in which a drum is provided and a long hose is wound around this rotating drum. However, storing an 8m long hose requires a large storage space, making the vacuum cleaner larger.

For this reason, it is possible to use a stretchable long hose, but
The structure described in Japanese Patent No. 127473 cannot be stored in a contracted state, and it is difficult to reduce the storage space even if a stretchable material is used.

This invention was made in view of the above points, and it is an object of the present invention to provide a hose storage device for a vacuum cleaner that can store a long telescopic hose in a small space and also maintains a stable storage condition. With the goal.

This invention forms a tapered hose storage box whose diameter decreases upwards at the top of the main case, which is provided with a dust collection section that is maintained in a negative pressure state, and the lower part of this hose storage box. A cylindrical space is formed in which one end of the connecting pipe connected to the dust collecting section is located, and a suction hose whose one end is connected to the connecting pipe of this cylindrical space is formed by a retractable hose. The present invention is characterized in that the telescopic hoses are contracted and wound into a coil in the hose storage box and stored in a stacked state. Therefore, when the telescopic hoses are contracted, wound into a coil, and stored in a hose storage box in a piled state, even if the repulsive force of the telescoping hoses is large, the hose storage box will not move upward as it moves upward. Since the diameter is tapered, the extension of the telescopic hose is suppressed and it can be stored in the hose storage box in a stable state.Moreover, the space in the hose storage box is small compared to the length of the telescopic hose. It is designed to be relatively small.

An embodiment of this invention will be explained based on FIGS. 1 to 4. 1 is a main body case, and a hose storage box 2 is connected to the upper surface of the main body case 1. Inside this hose storage box 2, there is provided a substantially tapered cylinder 4 for winding a suction hose 3 as long as 8m in a coil shape and maintaining it in a stacked state.
A lid 5 is attached to the upper part of the hose storage box 2 so as to be openable and closable. The suction hose 3 is entirely formed by a telescopic hose 6.

Next, the inside of the main body case 1 is divided into two chambers 8 and 9 by a partition plate 7, as shown in FIG. is installed.
In the other chamber 9, a dust collection case 12, which is a dust collection section, is housed so as to be freely drawn out. The dust collection case 12 is box-shaped with an opening at the top, and a packing 13 fixed to the upper surface of the ceiling 9 is joined to its upper edge, an opening 14 is formed on the back side, and an opening 15 is formed on the side surface. There is. The side opening 15 is connected to the chamber 8 through a small hole 17 formed in the partition plate 7 while being kept airtight by packing 16. Also,
A flange 19 fixed to the opening edge of a breathable dust bag 18 and a rubber plate 20 are detachably held on the inside of the back surface of the dust collection case 12.

A cylindrical space 21 protruding into the chamber 9 is formed on the upper surface of the main body case 1, and one end of the retractable hose 6 is accommodated in this cylindrical space 21 while being contracted. Further, one end of the telescopic hose 6 is connected to the connecting pipe 22 while being fixed at the bottom of the cylindrical space 21 . This connecting tube 22 is made of a hard material, and the other end is elastically joined to the rubber plate 20 of the dust collection bag 18 and is airtightly connected to a small hole 23 formed in the rubber plate 20.

Note that the hose storage box 2 is formed with an upper-opening storage section 24 that utilizes a space facing above the chamber 8 to store accessories such as various suction tools.

In such a configuration, when the lid 5 is opened and the suction hose 3 is pulled out to drive the electric blower 11, the outside air containing dust flows from the suction hose 3 to the dust collection bag 1.
Only clean air that is sucked into the dust bag 8 and passed through the dust collection bag 18 flows from the opening 15 to the exhaust hole 10 via the chamber 8. Cleaning is performed in this way. In this case, the hose storage box 2 is raised upwardly and the length of the suction hose 3 to be pulled out is shortened by the height thereof, but the telescopic hose 6 stored in the cylindrical space 21 is compressed into the hose storage box. Therefore, the effective length of the suction hose 3 that can be drawn out can be increased, and accordingly, a wider area can be cleaned.

After use, connect the suction hose 3 along the inner surface of the cylinder 4.
It can be stored very easily by winding it into a coil. Electric blower 11 when stored
When driven, the telescopic hose 6 contracts due to negative pressure.
Storage work can be further facilitated. The wound suction hose 3 is wound in an orderly manner, so there is no part where bending stress is concentrated, and there is no possibility of damage.

Moreover, the cylindrical space 21 can be formed within the space for connecting the telescopic hose 6 to the dust collection case 12, and therefore, the height of the hose storage box 2 can be prevented from increasing.

In addition, the suction hose 3 is entirely connected to a telescopic hose 6.
However, it is also possible to use the telescopic hose 6 for at least a part of the side connected to the dust collection part and use a simple flexible hose 25 for the main part. A means for connecting the telescopic hose 6 and the flexible hose 25 is shown in FIGS. 5 to 7.

The means shown in FIG. 5 is one in which a flexible hose 25 and a retractable hose 6 are fitted around the outer periphery of a connecting pipe 28 having flanges 26 and 27, and an adhesive 29 is filled in the fitting portion between them. be.

In the example shown in FIG. 6, a flexible hose 25 is fitted around a connecting pipe 30 having a flange 27, and the fitting portion is filled with adhesive 29. An expandable hose 6 is fitted around a connecting pipe 32 having flanges 27 and 31, and the fitting portion is filled with adhesive 29.
The two are fixedly fitted together.

In the case shown in FIG. 7, a flexible hose 25 is fitted into a connecting pipe 33 having a flange 27 while being filled with adhesive 29, and a flexible hose 25 is fitted into a connecting pipe 33 having a collar 27, and a flexible hose 25 is fitted into a connecting pipe 33 having a collar 27.
4, and the ring screw 35 is rotatably attached to the connecting pipe 34 while being prevented from coming off by the collar 36.
This ring screw 35 is screwed into a screw 37 formed on the other connecting pipe 33.

In both cases, the flange 27 can increase the strength to prevent the fitting portion from coming off together with the drying adhesive 29.

Since this invention is constructed as described above, the suction hose can be stored very easily in the hose storage box with a small space, and the suction hose can be wound in an orderly manner to prevent damage. Furthermore, when in use, the suction hose is pulled out from the hose storage box, but by stretching the retractable hose that has been compressed and stored in the cylindrical space, the effective length of the hose can be extended and a wider area can be cleaned. The cylindrical space simply reduces and stores the retractable hose, and can be formed by effectively utilizing the dead space of the main body case.This allows the height of the hose storage box to be lowered.
In particular, even if the repulsive force that tries to extend the telescopic hose is large, the hose storage box is tapered so that the diameter decreases toward the top. It has the advantage of being able to be stored in a
