Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner hose storage device that compactly stores a long hose.

Conventionally, when storing long hoses as long as 8 meters, they are wound into a ring and bundled and hung on a hook, or stored in a special storage box. However, bundling long hoses is a difficult task and requires a considerable amount of storage space, which is not aesthetically pleasing. In addition, when storing long hoses in a storage box, the long hoses are stored randomly, making the storage box quite large.Furthermore, the hoses become tangled and are difficult to remove, making it difficult to use. ing. Moreover, there is also a problem in that the hose has parts where it bends sharply and is easily damaged.

The present invention has been made in view of the above points, and an object of the present invention is to obtain a hose storage device for a vacuum cleaner that can be easily stored in a small space without applying excessive force to the flexible hose. .

The present invention forms a bottomed cylindrical hose storage tube with a circular inner peripheral surface, and attaches an end of a flexible hose to the outer circumferential side of the bottom surface of the hose storage tube, and sets the height of the hose storage tube to the above. The flexible hose is set according to the height of the contracted and spirally wound state, and a diameter smaller than the inner diameter of the hose storage tube by at least the diameter of the flexible hose is installed in the opening of the hose storage section. It is characterized by providing a funnel-shaped hose guide frame with a guide opening formed in the center. Therefore, the flexible hose does not have any parts that are bent strongly below the curvature of the inner circumferential surface of the hose storage cylinder, so there is no risk of damage, and the flexible hose can be contracted into the storage area and wound in a spiral shape. A long flexible hose can be stored in a small space, and since the hose guide frame with a guide opening in the center is funnel-shaped when stored, it is easy to store the hose. Since the diameter of the guide opening is smaller than the inner diameter of the hose storage tube by at least the diameter of the flexible hose, the flexible hose can be reliably kept in the stored state after storage, and it will be stored neatly when pulled out. It is designed so that it is easy to use and does not tangle with each other.

A first embodiment of the present invention will be described based on FIGS. 1 to 6. First, a hose storage case 1 is formed in the shape of a rectangular parallelepiped, and this hose storage case 1 is a combination of an outer case 2 and a hose storage body 3. The outer case 2 has a box shape with an outer surface 4 having a rectangular shape, and a funnel-shaped hose guide frame 7 having a guide opening 6 at the center thereof is formed on the upper surface 5. The edge 8 of the guide opening 6 is curled to have a smooth inner peripheral surface. Next, the hose storage body 3 has a vertical wall 9 on which the outer case 2 is fitted, and a flange 10 that contacts the floor surface.
The hose storage cylinder 14 has a base 11, and a hose storage tube 14 having a circular inner circumferential surface 12 and an opening 13 at the top, and a bottom surface 15 are formed on the base 11. The upper end of the hose storage cylinder 14 is in contact with the hose guide frame 7. Further, a protrusion 16 is formed at the center of the bottom surface 15 and projects upward. The outer peripheral surface of this protrusion 16 and the inner peripheral surface 12
The distance between the protrusion 16 and the protrusion 16 is large enough to fit a flexible hose to be described later, and the upper part of the protrusion 16 is formed into a spherical shape.

Next, a recess 17 is formed in the bottom surface 15, and a connecting tube 18 protruding downward is provided in the recess 17.
are integrally formed. A flexible connection hose 19 is connected to this connection tube 18, and this flexible connection hose 19 is pulled out through a notch 20 formed in the base 11 and the outer case 2, and is attached to its end. A connecting portion 22 is formed which is detachably connected to a vacuum cleaner 21. An L-shaped connecting tube 24 formed at one end of the flexible hose 23 is inserted into and removed from the recess 17, and an annular groove 25 is formed in the connecting tube 24. Further, the connecting pipe 24 is provided in the recess 17.
A locking device 26 is provided to removably hold the. The locking device 26 includes a compression spring 27 and a clamp 28 biased by the compression spring 27. The clamp 28 is formed with a projection 29 that fits into the annular groove 25 and a grip portion 30.

A grip tube 31 bent in a dogleg shape is provided at the other end of the flexible hose 23, and an extension tube 32 and a suction port body 33 are sequentially connected to the grip tube 31 in a detachable manner. .

Next, the height of the hose storage cylinder 14 corresponds to the height of the flexible hoses 23 that are contracted and stacked in a spiral shape, and the grip tube 31 is provided on the upper surface 5 of the case 2. A grip tube fixing portion 34 to be fixed is formed. The grip tube fixing portion 34 is composed of a grip tube groove 35, and a grip tube presser 37 that fits into the inner periphery of the grip tube 31 is formed on an end surface 36 of the grip tube fixing portion 34. Note that 38 is a remote switch.

When using this configuration, as shown in FIG. 1, the hose storage case 1 and the vacuum cleaner 21 are placed in a fixed position, and the flexible hose 23 is pulled out to perform cleaning. The length of this flexible hose 23 is generally about 8 m. To store it, remove the extension tube 32 from the grip tube 31, and press the opening of the grip tube 31 with your hand while driving the vacuum cleaner 21 with the remote switch 38, and the flexible hose 23 will close due to negative pressure. Start shrinking. At this time, the flexible hose is subjected to mechanical resistance at the hose guide frame 7, so it contracts from the base side and is guided by the protrusions 16 in a spiral manner along the inner circumferential surface 15 of the hose storage tube 14. The grip tubes 31 are stacked up and finally the grip tube fixing part 3
Fixed by 4. Then, the operation of the vacuum cleaner 21 is stopped by the remote switch 38, and the flexible connection hose 19 is pulled out, thereby completing the storage operation. At this time, the flexible hose 23 tries to expand due to its self-righting force, but since the grip tube 31 is fixed, it will not spring out. In particular, the diameter of the guide opening 6 of the hose guide frame 7 is smaller than that of the hose storage tube 1.
4 is set smaller than the inner diameter dimension of the flexible hose 23 by at least the diameter dimension of the flexible hose 23,
There is no upward protrusion. In addition, the flexible hose 23
When you pull it out, it has its own restoring force, so it can be pulled out very easily. Furthermore, there is no risk of the flexible hose 23 getting tangled at this time.

Next, a second embodiment of the present invention will be described based on FIGS. 7 and 8. The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, the height of the base 11 is increased, a partition wall 39 is provided inside the base 11, and a bottom plate 40 is also provided, thereby forming a dust collection chamber 41 and a power chamber 42. A dust collecting container 43 connected to the connecting pipe 24 and a filter unit 44 are provided in the dust collecting chamber 41. The dust collection container 4
3 is formed in the shape of a drawer so as to be removable from the outer surface 4 of the outer case 2. In addition, the electric power chamber 4
An electric blower 45 is attached to the filter unit 2, and this electric blower 45 is connected to the filter unit 44 via a main packing 46. Furthermore, an exhaust passage 47 is provided between the outer case 2 and the hose storage tube 14.
An exhaust hole 48 is formed in the outer case 2.

With this configuration, there is no need to connect a vacuum cleaner and everything can be used as a unit, and even if the room is quite large, just setting it in one corner will be enough to clean that room. I can do it.

As described above, the present invention reduces the size of the flexible hose and stores it in the hose storage tube in a spirally wound state, so even if the hose storage tube is small, a fairly long flexible hose can be stored. can be stored,
At this time, there is no risk of damaging the flexible hose.
It is easy to handle without the risk of getting tangled when pulled out, and the protrusion formed on the bottom guides the base of the flexible hose, allowing for secure storage.Moreover, the hose guide frame is shaped like a funnel. Therefore, it is easy to store the flexible hose, and since the diameter of the guide opening of the hose guide frame is smaller than the inner diameter of the hose storage tube by at least the diameter of the flexible hose, the flexible hose can be securely stored after storage. This has the advantage of being able to maintain the stored state.
