Abstract

PURPOSE:To make the cleaner compact at the time when it is housed, and to obviate its torsion at the time when it is used by allowing a hose to have a spiral winding habit, and also, providing a rotary mechanism on its end part. CONSTITUTION:A hose 10 has a spiral winding habit, and contracts in a state that a spiral winding pitch is small, in the case of a state that it is left naturally. Also, a rotary mechanism is used for a connecting part of the hose 10 and a hose grip part 11. For instance, a hose connecting pipe 7 and the hose grip part 11 are rotatable each other by an O-ring 8, and also, are held airtightly. Also, it is prevented by a fall-out stop pin 9 from that the hose connecting pipe 7 falls out of the hose grip part 11. Therefore, by holding and drawing the hose grip part 11 at the time of using the vacuum cleaner, it is extended to a state that a spiral winding pitch is large, and a distance between a cleaner main body 1 and the hose grip branch 11 is lengthened. Also, since the rotary mechanism is provided, a torsion caused by expansion and contraction of the hose 10 can be obviated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner having a highly convenient hose.

2. Description of the Related Art In general, the longer the hose of a vacuum cleaner is, the more convenient it is to use, but the longer the hose is, the more inconvenient it is to store.Therefore, various ideas are being sought.

27, -7 A conventional vacuum cleaner will be explained with reference to FIG.

In the figure, reference numeral 1 denotes a vacuum cleaner body, which includes an intake motor 12 and a dust collection bag 13. The hose 2 is connected to a hose handle portion 3 and a main body side connection portion 4 to form a hose unit. In addition, 5 in the figure is an extension pipe, and 6 is a floor nozzle.

Dust sucked in through the floor nozzle/L/6 is removed from the extension tube 6° hose handle 3. The dust passes through the hose 2 and is captured in the dust collection bag 13.

Problems to be Solved by the Invention In such conventional vacuum cleaners, a long hose 2 is convenient during use, but it is inconvenient when stored, which is a contradictory problem. The present invention solves the above problems and aims to provide a vacuum cleaner with excellent operability and handling.

Means for Solving the Problems In order to achieve the above object, the present invention provides a hose having a spiral winding with a small winding pitch. Further, a rotation mechanism that can freely rotate is provided at either or both of the hose handle 3 and 7 side connection portions of the hose, or the hose body side connection portion.

Function The present invention has the above-described configuration, and when a vacuum cleaner is used, the spirally formed hose is stretched out to a state where the spiral winding pitch is increased by applying a tension between both ends. When stored, the spiral winding pitch becomes small.

In addition, the rotation mechanism provided at the connection part of the hose eliminates twisting caused by expansion and contraction of the hose during frequent use.

, Example Hereinafter, an example of the vacuum cleaner of the present invention will be described with reference to FIGS. 1 and 2. Note that the same numbers are used for the same constituent members as those explained in the conventional example.

As shown in FIG. 1, the hose 1o has a spiral winding, and when left alone, the hose 1o shrinks with a small spiral winding pitch. Furthermore, as shown in FIG. 2, a rotation mechanism is used at the connection between the hose 1o and the hose handle 11. That is, the hose 1o is fixed to the hose connection pipe 7, and the connection pipe 7 and the hose handle 11 are rotatable with respect to each other by the O-ring 8, and are kept airtight. A retaining pin 9 prevents the hose connection pipe 7 from falling out from the hose handle 11. The configuration of the other portion is the same as that of the conventional example, so a description thereof will be omitted.

To explain the operation in the above configuration, when using the vacuum cleaner, if you hold the hose handle 11 and pull it, the spiral winding pitch will be stretched to a larger state, and the vacuum cleaner body 1 and the hose handle 11 will be stretched out. The distance becomes longer. Furthermore, since it has a rotation mechanism, it is possible to eliminate twisting caused by expansion and contraction of the hose 10.

Although this embodiment has been described with respect to a vacuum cleaner, it goes without saying that the present invention can also be applied to a central cleaner that requires a long hose. The rotation mechanism is still hose 1o.
The main body side connecting portion 4 can also be provided in exactly the same manner.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, by forming a spiral winding on the hose, the hose is not long when in use, and can be made short and compact when stored.

By providing the rotating mechanism, it is possible to eliminate twisting of the hose during frequent use, so it is possible to provide a vacuum cleaner with excellent operability and handling.
