Description

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

Conventionally, when storing a long flexible vacuum cleaner hose up to 8 meters in length, the hose must be wound into a ring, bundled, and hung on a hook, or stored in a special storage box. There is. However, bundling long hoses is a difficult task and is not aesthetically pleasing. Long hoses that are stored in special storage boxes have to be taken out when they are used, so in a small room, the length of the hoses that crawl on the floor increases and becomes a nuisance, making storage a hassle. In particular, long hoses have irregular storage configurations, and depending on how you put them in, you may not be able to store them all, making them difficult to take in and out, and some parts are bent with a small radius of curvature, which can lead to damage.

Furthermore, as described in Japanese Patent Application Laid-Open No. 50-16366, there is a device in which a drum around which a flexible hose is wound is rotatably attached to a main body case equipped with an electric chamber and a dust collection chamber. This type of device has the disadvantage that the outlet for the flexible hose is located below the main body case, and that the operation for storing the flexible hose is extremely troublesome and the structure is complicated.

This idea was made in consideration of the above points, and allows the flexible hose to be easily stored in a small space without applying excessive force, and in particular, allows the flexible hose to be easily pulled out when in use. The purpose is to provide a hose storage device for a vacuum cleaner.

This invention enables the flexible hose to be stored regularly and orderly in the storage chamber in a spiral manner in a contracted state that has a restoring force in the direction of extension by aligning the flexible hose along the inner circumferential wall of the storage chamber. By being stored in a storage chamber that expands as it goes downwards,
They do not float upward due to the force that spreads outward from the rolled state and due to their own weight, and are stacked one after another in a stable state, and there are no parts where the radius of curvature becomes smaller than necessary, which prevents damage and saves storage space. Furthermore, the flexible hose has a small winding diameter at the top and a large reaction force in the direction of expansion, so the flexible hose can be easily pulled out by the reaction force. It is.

An embodiment of this invention will be described based on the drawings. Reference numeral 1 denotes a main body case, and the lower part of this main case 1 is provided with legs 2 located on both the front and rear sides, a carrier 3 located further forward than the front legs 2, and a sled portion 4 is formed at the lower part of the front edge. has been done. Carrier 3 is normally off the floor and main body case 1
It rolls on the floor when you lean forward. Inside the main body case 1, there is formed a storage chamber 7 which is surrounded by a cylinder 5 or a rectangular tube and whose inner circumferential wall 6 is inclined so that the interior expands downward. In this storage chamber 7, a bellows-shaped flexible hose 9 having a restoring force of up to 8 m is housed in a spiral shape, one end of which is held in a connection port 8 formed at the bottom of the storage chamber 7. In addition, a downward reaction force is exerted by the inner circumferential wall 6 that expands downward, and the stored flexible hose 9 is maintained in a stable storage state without being displaced. Further, a hemispherical guide 10 is provided at the center of the bottom of the storage chamber 7. Further, a dust case 12, which is a dust collection part that houses a filter 11 and communicates with the connection port 8, is housed in the lower part of the main body case 1, and can be freely drawn out.
An electric chamber 14 for housing an electric blower 13 and an exhaust passage 15 are formed, and an exhaust cover 17 is attached to the exhaust passage 15, in which a large number of exhaust holes 16 are formed on the back, upper and lower surfaces, and both sides.

Next, an opening 18 expanding into a mortar shape is formed in the upper part of the storage chamber 7, and a groove 19 having a semicircular cross section is formed extending tangentially from a part of this opening 18. A protrusion 21 is formed in the groove 19 to engage with the tip of the grip tube 20 of the flexible hose 9 accommodated in the groove 19. Further, a handle 22 is formed at the upper front side of the main body case 1.

Next, a lid 23 is rotatably attached to the upper part of the main body case 1. A holding part 25 for removably holding accessories such as a floor brush 24 is attached to the inner surface of the lid 23, and an insertion part 26 for inserting the flexible hose 9 is formed in the front part of the lid 23. There is.

In such a configuration, the flexible hose 9 stored in the storage chamber 7 is stored under a downward reaction force exerted by the inner circumferential wall 6 that expands downward in the storage chamber 7, and the flexible hose 9 is The hose 9 is maintained in a stable storage state with no displacement. The lid 23 is opened, the grip tube 20 is picked up, and the flexible hose 9 is pulled out, but the winding diameter of the flexible hose 9 becomes smaller toward the top, and the reaction force in the expanding direction is stronger. The reaction force is applied to the flexible hose 9 after the end of the flexible hose 9 is pulled out.
This allows the long flexible hose 9 to be easily pulled out. Even if the lid 23 is closed in this state, the flexible hose 9 will not be crushed or damaged due to the formation of the insertion portion 26.

In this state, when the electric blower 13 is driven, outside air containing dust is sucked into the dust case 12 from the flexible hose 9. Since the exhaust air is dispersed and exhausted from the exhaust holes 16 formed on all sides of the exhaust cover 17, the wind blowing on the person is extremely weak and the exhaust noise is also small. After cleaning, when the electric blower 13 is driven with one end of the grip tube 20 closed by hand, the flexible hose 9 exhibits a shrinking action due to negative pressure, and the flexible hose 9 is simply fed in without resisting the force and stored. It can be stored in chamber 7. In the case of a flexible hose that does not have a bellows shape and has a very small amount of expansion and contraction, it can be fed by hand without using negative pressure.

In this manner, the storage work can be easily performed by winding the flexible hose 9 along the inner surface of the storage chamber 7. Furthermore, although the flexible hose 9 has a force to expand in the expanding direction, the inner circumferential wall 6 of the storage chamber 7 is inclined so that it becomes wider as it goes downward, so the flexible hose 9 does not float upward but can be moved downward. Stabilize. In this state, there is no part of the flexible hose 9 that is locally bent at a small radius, and no damage occurs.
The reaction force in the direction of extension of the contracted flexible hose 9 acts as an engagement force between the grip tube 20 and the protrusion 21 .
The guide 10 of the storage chamber 7, together with the inner peripheral wall 6, guides the winding of the flexible hose 9 during storage.
Since it is urged in the expansion direction by its own elasticity, it may be omitted as shown in FIG.

Note that the connection port 8 may be connected to a dust collecting section of a vacuum cleaner provided separately outside the main body case 1.

Since this invention is constructed as described above, the flexible hose can be easily wound along the inner circumferential wall of the cylindrical storage chamber, and all the flexible hoses can be stored in a regular manner. Since the circumferential wall is inclined in such a direction that the room becomes wider as it goes downwards, the flexible hose itself is stably housed downward due to the force of expanding outward, and the inner circumferential wall that expands downward allows the flexible hose to be accommodated downwardly. Since there is a reaction force to
It is possible to maintain a stable storage state without shifting the position, and even when the flexible hose is pulled out halfway and stored again after use, it can be stored in a stable state, and furthermore, it becomes smaller. Parts can also be prevented from being damaged,
Storage space can be reduced, and
The flexible hose has a small winding diameter at the top and a large reaction force in the expansion direction. Therefore, the long flexible hose can be easily pulled out by the reaction force.
