BRIEF SUMMARY
BACKGROUND OF THE INVENTION
In conventional carpet washing machines the distributing unit for the detergent fluid and the scavenging agent are transferred in the direction of the rolls and with the nozzles of the distributing unit, the detergent fluid and/or the scavenging agent are sprayed on the surface of the carpet. In these machines, a separate source of power and a mechanism is needed for moving the distributing unit. This moving mechanism is positioned inside the frame of the machine and forms a part of the distributing unit. The mechanism, disposed inside the frame, is subject to very humid conditions and it is either expensive or undependable. The drying devices are positioned after the rolls and arranged to blow dry air on the surfaces of the carpets. The dryers used in conventional carpet washing machines are not efficient.
The purpose of the invention is to provide a machine for washing carpets, wherein the distributing unit of the detergent fluid and/or the scavenging agent is arranged to be moved by a simple and cost effective construction. Additionally, the aim with the invention is to provide a machine for washing carpets, wherein the drying device is simple in construction and efficient.
SUMMARY OF THE INVENTION
30 The goal of the invention is achieved by providing a machine for washing carpets, to which belongs a frame, inside the frame placed rolls, supported on which, the carpet is arranged to be transferred in the machine, inside the frame is positioned, in the length direction of the rolls, a movable distributing unit for detergent fluid and scavenging agent for spraying the detergent fluid and the scavenging agent on the surface of the carpet, and connected to the distributing unit are hoses for the detergent fluid and the scavenging agent, which are led from the inside of the frame out.
In the machine in accordance with the invention, the hoses of the detergent fluid and the scavenging agent are outside the machine at one end and connected with a transportation device fastened on the frame. The transportation device is arranged to transfer the hoses which in turn moves a distributing unit connected to the other end of the hoses. The transportation device is positioned outside the frame and does not exist in humid conditions. The rolls are placed inside the frame. The hoses are moved simultaneously (one for the transferring of the detergent fluid and the other the scavenging agent) to the distributing unit for the moving of the distributing unit. In the machine in accordance with the invention one advantage is that the hoses are always straight inside the frame, so that they are not bowed into sharp angles and break easily as they do in conventional machines.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will be explained in more detail by referring to the attached drawings in which:
FIG. 1 presents an embodiment of the machine for washing carpets in accordance with the invention seen from the side in two different cutthroughs,
FIG. 2 presents the machine in accordance with FIG. 1 seen from the gable, and
FIG. 3 presents the machine in accordance with FIG. 1 seen from the gable with the gable cover opened.
DETAILED DESCRIPTION OF THE INVENTION
In the embodiment in accordance with FIGS. 1-3 a machine for washing carpets is shown. The machine has a frame 1. Disposed inside the frame are rolls 2, a distributing unit 4, hoses 5, 6, which have been led from the inside of the frame to the outside. Outside the frame is placed a transportation device 7. In this embodiment, the machine has five rolls 2, four rolls have been arranged by pairs with the fifth placed in the middle of the roll pairs at a distance therefrom. In accordance with the FIG. 3, the carpet 3 is fed into the machine from an opening on the left side of the frame 1, transferred inside the machine supported by the rolls 2 and fed-out through the opening 10 on the right side of the machine. The distributing unit 4 for the detergent fluid and the scavenging agent is placed between the rolls 2 and it is moved
