Description
- The present invention finds application in the field of cleaning machines and particularly relates to a hose intended for use in machines for cleaning walls, floors, moquettes, carpets and the like.
- A number of telescopic hose arrangements for vacuum cleaners and similar electrical appliances are known. Particularly, European Patent No. 1 092 383 describes a telescopic extension comprising an outer hose, a second hose sliding within the first hose and a device for locking the two hoses to each other, operable by means of a sliding device. This arrangement allows to adjust the length of the assembly formed by the two hoses. An apparent limitation thereof consist in that the two serially disposed hoses form a single duct and allow the passage of one fluid only.
- European Patent No. 0 848 926 discloses a device for joining two vacuum cleaner hoses by means of a telescopic connection. Such an arrangement allows air to flow inside the assembly and also includes an extendible election cable for transmitting signals and power between the two hose portions. Like in the previous arrangement, the telescopic connection provides convenience and ease of use, however it does not allow the passage of an additional fluid, such as for instance steam.
- European Patent No. 0 873 713 describes a one-piece rigid hose, comprising a suction duct and a delivery duct arranged externally to the suction duct. The delivery duct may be used to convey a cleaning fluid or liquid, such as steam, on the object or surface to be cleaned, whereas the suction duct may be employed to remove dust and dirt. A drawback of this arrangement consists in that the hose has a fixed length. Thus, the rigid hose cannot be readily extended to clean surfaces at the floor level or shortened to clean surfaces or objects which are situated closer to the user or in narrow places. An additional drawback of this arrangement is that the hose is made from one single piece. Hence, any damage or defect of one of the two ducts requires the replacement of the whole piece, thus resulting in increased service and repair costs.
- European Patents No. 0 558 460, 0 601 981 and 1 122 482 describes a flexible hose designed for application in the field of cleaning machine, comprising a first duct for air suction and a second duct for delivering a cleaning liquid or fluid onto the surface to be cleaned. The flexible hose renders the overall machine easier to be used, as compared with a rigid hose, however has the limitation that its length is approximately fixed. In fact, in certain cases, the possibility to shorten or to extend the overall hose may facilitates cleaning operations in narrow spaces or over surfaces far from the user respectively.
- A general object of the present invention is to obviate the above mentioned drawbacks, by providing a reliable and cost-effective hose for cleaning machine.
- A main object is to provide an effective and easy-to-use cleaner hose for cleaning objects and surfaces of different types.
- A particular object of the invention is to provide a hose which is readily and conveniently adaptable to clean objects and surfaces at varying distances from the user, both in wide places and in narrow areas or corners.
- An additional object of the invention is to provide a hose that can be handled safely, by avoiding any contact between the user and a locally overheated area, and any outflow of hot fluids.
- Yet another particular object is to provide a strong hose, whose features remain unchanged overtime.
- An additional particular object is to provide a hose whose parts may be easily assembled and replaced, in case of faults or malfunctioning.
- These objects as well as other which will be more clearly hereinafter, are achieved by providing in accordance with
claim 1, a hose for wall-, floor-, carpeting-, carpet- and the like cleaning machine, comprising at least one first rigid tubular member, having at least one air and liquid suction duct, and at least one steam or other fluid delivery duct, the ducts being reciprocally connected along their longitudinal and parallel axes, characterised in that it comprises at least one second rigid tubular member similar to the first tubular member and having at least one air and liquid suction duct and at least one steam or other fluid delivery duct, the two tubular ducts being slidably and telescopically coupled, in such a manner as to allow arbitrary adjustment of the overall hose extension. - Thanks to this particular configuration, an easy-to-use hose may be obtained for cleaning objects and surfaces of different types, which may be readily and conveniently adapted to clean objects and surfaces at varying distances from the user, both in wide places and in narrow areas or corners.
- Preferably, each tubular member has an elongate protection member for thermally insulating its respective steam or other fluid delivery duct and preventing any direct contact therewith by users. Each protection member is disposed substantially parallel to its respective delivery duct and is substantially as long as the latter for fully heat insulating it from the environment.
- Thanks to these particular features, the hose can be safely handled thus avoiding any contact between the user and a locally overheated area, and any outflow of hot fluids, regardless of the relative position of the two tubular members.
- Further features and advantages will be more clearly apparent from the detailed description of a few preferred, non-exclusive embodiments of a cleaner hose according to the invention, which are described by way of non-limiting examples with the assistance of the annexed drawings, in which:
