Description

[Detailed Description of the Invention] The present invention relates to a vacuum cleaner hose storage device that is buried when not in use and protrudes when in use so that the hose can be pulled out.

Dust suction hoses that suck dust together with air have become longer and longer in recent years, and recently, large cleaners called central cleaners have been installed in specific rooms, and piping has been installed in each room of the house. Cleaning is done by carrying only the hose.

Since the dust suction hoses are becoming longer and longer, it has become possible to store the hoses on a reel, thereby eliminating the need to carry the hoses to each room each time the cleaning is done.

In addition, it has become possible to install the hose reel in a place where it can protrude or be buried inside the floor or wall, or inside the vacuum cleaner body.

The present invention has been developed to obtain the effects described below under the above circumstances, and will be explained with reference to the drawings showing the embodiments thereof.

In FIG. 1, reference numeral 1 denotes a floor or wall surface, and a cylindrical box-shaped case 2 is attached inside the floor or wall surface.

An opening 3 in the floor or wall surface 1 with which the entrance of the case 2 contacts is provided with a ring 4 having a spring pressure that contracts in the inner diameter direction.

Reference numeral 5 denotes a hose storage body for storing a hose, which is made in a cylindrical shape, and grooves 6 and 7 are provided at the upper and lower peripheral edges of the hose storage body 5, respectively, with which the ring 4 engages.

A reel-shaped winding frame 8 is rotatably attached inside the hose storage body 5.

Flanges 9 and 10 are attached to both ends of the winding frame 8, and a dust suction hose 11 is wound between these flanges.

The dust suction hose 11 is made of flexible synthetic resin, and has the function of transporting the dust sucked in together with the air to the main body of the vacuum cleaner.

One end of the dust suction hose 11 is connected to a suction port 1 protruding from the winding frame 8.
2, and the other end engages with a hose outlet 13 opened on the outer periphery of the hose storage body 5.

The outside of the flange 9 is a spring box 14,
A mainspring 15 is attached inside it.

One end of the mainspring 15 is fixed to the mainspring box, and the other end is fixed to the mainspring shaft 16.

The other end of the winding frame 8 is rotatably supported by an end plate 18 of the hose storage body 5, and is kept airtight via a backing 17.

The end plate 18 also serves as a bearing for the winding frame 8, and communicates the hollow central axis of the winding frame 8 with the center of the bottom plate 20 of the case 2 via a bellows 19.

21 is a pipe that communicates with the vacuum cleaner body through under the floor or through the wall.

Reference numeral 22 denotes a brake knob, which is provided so as to be led out to the outside of the hose storage body 5. By pressing this knob, the brake 24 is released via the brake frame 23.

The brake 24 is constantly in contact with the outer periphery of the spring box 14 due to the tensile force of the spring 25, and applies a braking force to the spring box.

The mainspring 15 connects the dust suction hose 11 to the hose outlet 1.
3, the power spring is stored in the mainspring, and by pressing the brake knob 22, the winding frame 8 is rotated to wind up the dust suction hose 11.

The mainspring shaft 16 is fixed to the end plate of the hose storage body 5.

Since the present invention is constructed as described above, when the vacuum cleaner is not in use, the hose storage body 5 is pushed into the case 2 as shown in FIG. 5 is kept buried in case 2.

Thereby, the hose storage body 5 does not get in the way.

When using the vacuum cleaner, the hose housing 5 is pulled out from the case 2 using a handle (not shown), and the dust suction hose 11 is pulled out from the hose outlet 13 on the side of the hose housing 5 in a protruding state. Attach an extension pipe and dust inlet to suck in dust along with air.

The dust-containing air enters the winding frame 8 through the hose 11, and is sucked into the vacuum cleaner body through the bellows 19 and the pipe 21.

When the cleaning is finished and the brake knob 22 is pressed, the dust suction hose 11 is wound around the winding frame 8 in the hose storage body 5 protruding from the floor or wall surface due to the accumulated force of the mainspring 15.

When the end of the hose 11 is plugged and the hose storage body 5 is pushed into the case 2, the bellows 19 is contracted and the hose storage body 5 is attached to the floor or wall surface 1 by the engagement of the groove 6 and the ring 4. It is held buried in the case 2.

FIG. 3 shows a state in which the vacuum cleaner is being driven with the case and hose storage body attached to the wall, and the hose storage body 5 is attached to the winding frame 8.
Since it can be rotated around the axis, the cleaning range can also be rotated freely as shown by the arrow.

FIG. 4 shows the case 2 and the hose storage body 5 installed on the floor, and in this case also the hose storage body 5 is placed on the winding frame
Since it is rotatable around the axis, it can be moved freely around the cleaning area as shown by the arrow.

26 in FIG. 3 indicates a wall surface, and 27 in FIG. 4 indicates a floor surface.

Although FIGS. 1 to 4 illustrate the case where a large cleaner such as a central cleaner is used as the main body of the vacuum cleaner, it is also possible to use a general cleaner.

Figure 5 shows the case when used in a portable vacuum cleaner.
The vacuum cleaner is shown when not in use, and the hose storage body 5 is shown pushed into the case.

28 is the vacuum cleaner body, 29 is the wheel for movement, and 30
is a caster.

31 is a push button, and by pressing this button, the hose storage body 5
protrudes from the case.

32 is a handle of the vacuum cleaner. FIG. 6 shows the vacuum cleaner in use, with the hose storage body 5 protruding from the case.

In this case as well, the direction of the dust suction hose 11 can be freely changed.

The present invention explained above has the following advantages because it has the structure described in the claims of the above-mentioned utility model registration.

By providing a hose storage body with a hose outlet on the side surface through which the hose can be taken in and taken out so that it can be protruded into the wall, floor, or vacuum cleaner body, the hose storage body can only be inserted into the hose storage body when the hose storage body is protruded. The hose can be wound and unwound against the reel.

Therefore, there is no need to bundle the hoses and place them in a corner of the room when the vacuum cleaner is not in use, or to store hooks on the inner surface of the lid of the vacuum cleaner body, making the hoses easy and compact to store.

The hose storage state can be easily obtained by simply pushing the hose storage body, and the hose storage body can be held in the buried state even though a bellows is used due to the engagement of the ring and the groove. .

Moreover, in this hose storage state, the hose storage body does not protrude from the wall or floor, so it has a good appearance and does not get in the way of pedestrian traffic. Damage can be prevented.

Furthermore, the hose storage body is rotatable, and in a state where it is held protruding from a wall surface etc. by engagement with the ring and the groove,
Since the hose is pulled out from the side for cleaning, the hose storage body can be easily rotated during cleaning work, widening the cleaning range, and the easy rotation of the hose storage body prevents undue force on the hose. This prevents hose damage to a large extent.

Moreover, since the concave groove of the hose storage body engages and disengages from the ring,
By pulling out the hose storage unit forcefully, it can be removed from an opening in a wall or floor, and this combined with the use of bellows makes it easy to repair or replace hoses, etc. if necessary. Can be disassembled.

Further, since the bellows is provided, a pressing force can be obtained when the bellows is expanded from the shortened state when the hose storage body is pulled out.

This allows the relatively large and heavy hose storage body to be easily pulled out.
