Problems solved by technology

This would lead to say that the brush unit is not universally applicable to any vacuum cleaner with a hose and tube, because the vacuum cleaner must be provided with a power outlet, a cable in the hose and tube, and some Connection element for electrical connection of cleaning device
A separate electric motor in the brush unit is also likely to make the brush unit more expensive to manufacture

Embodiment Construction

[0030] in the attached picture figure 1 and figure 2 The appearance of a carpet cleaning device according to an exemplary embodiment of the present invention is shown. The overall design of the carpet cleaning device is somewhat similar to a normal nozzle unit of a vacuum cleaner, with a tubular connection sleeve 1 adapted to be connected to the outer end of the tube of a vacuum cleaner with hose and tube. However, this carpet cleaning device is slightly different from ordinary suction nozzle units in that it also includes a cover 2 covering the powder containing chamber, an optional air inlet 3 and adjustable operating levers 4, 5, said operating levers 4, 5 is used to open and close the air inlet and control powder distribution, which will be described separately below.

[0031] see now Figure 3-Figure 6 . From which the mechanical structure of the device can be seen in detail. A radial flow turbine 6 is arranged at the rear of the carpet cleaning device, just before t...

Abstract

The invention relates to a carpet cleaning device being connectible to a vacuum cleaner provided with a hose and tube (7). The carpet cleaning device has an elongated air suction opening (11) facing the carpet to be cleaned, through which air can be drawn. A rotatably driven brush (10) is positioned in the air suction opening to accomplish agitation of the carpet surface. A valve means (12) is arranged for allowing switching of the air flow through the air suction opening or an alternative air inlet (3). The device also comprises a dispensing unit for the cleaning agent, which is driven by a driving means powered from a power source excluding a mains supply network, and a rotatable turbine wheel (6), which is rotatably driven by the air flow drawn by the vacuum cleaner through the tube (7). At least the brush is rotatably driven by the turbine wheel, wherein the device is formed such that the air flow is passing the turbine wheel when air is drawn through the air suction opening (11) as well as through the alternative air inlet (3). The invention also relates to a method for cleaning of carpets.

Description

technical field [0001] The present invention relates to a carpet cleaning device suitable for cleaning carpets with cleaning agents and capable of being connected to a vacuum cleaner with a hose and tube, the device comprising: [0002] Connection structures for allowing connection to vacuum cleaners; [0003] an elongated air intake adapted to face directly against the carpet to be cleaned and through which air can be drawn from an area adjacent to the surface of the carpet to thereby draw dirt from the carpet; [0004] Rotatably driven brushes located in said air intake to achieve agitation of the carpet surface and to be able to introduce cleaning agent between the fibers of the carpet and to facilitate cleaning after a desired time of application of the cleaning agent the cleaning agent is released from the carpet along with the soil, allowing suction through the air intake with an air flow; [0005] A valve member for allowing air flow to be switched between a suction s...
