DESCRIPTION:
BRIEF SUMMARY
The object of the invention is a device for washing of carpets, in particular fibre carpets, to which device belong rolls, supported on which the carpet is arranged to be conveyed within the device, to which rolls belong a supporting roll to support the carpet during the washing process and a rinsing roll, located at a distance from the supporting roll, to support the carpet during the rinsing process.
To the carpets made of artificial and natural fibres belong a relatively stiff bottom layer made of rubber or corresponding material and a fibre layer fixed to the bottom layer. These carpets cannot be washed in normal washing machines due to their stiff bottom structure. The problem is the washing of the big carpets efficiently and at low costs. Nowadays the carpets are generally washed by hand using auxiliary equipment, whereby the costs are high. Washing contrivances have been developed, in which the carpets are cleaned through conveying them supported on rolls e.g. in different kinds of washing basins and by brushing them during the process in order to remove the dirt. The brushing, however, wears and tears to a great extent the carpets and the time of usage for them is shortened. With the help of the present washing devices the carpets cannot be washed efficiently.
The aim of the invention is to bring forth a washing device, which eliminates the disadvantages in the present washing contrivances for carpets. In particular the aim with the invention is to bring forward a device for the washing of carpets, by means of which the carpets made of artificial and natural fibres can be washed efficiently and at low costs. The aim of the invention is additionally to bring forth a device for washing of the carpets, which is easy to use and dependable in operation.
The aim of the invention is reached by means of the device, which mainly is characterized in that, what is presented in claims.
In the device according to the invention between the supporting roll and the rinsing roll a washing and rinsing apparatus is placed, which is arranged to flush under pressure being liquid detergent on the surface of the carpet located on the supporting roll and liquid scavenging agent on the surface of the carpet located on the rinsing roll. Hereby the carpet is washed efficiently, because the detergent and the scavenging agent can be flushed on the surface of the carpet at a high pressure, favourably at a pressure of 100 kp/cm.sup.2, whereby an efficient cleaning action is reached. The device is simple and efficient and the pressure of the detergent and scavenging agent flushes can be regulated to conform with the dirtness and the quality of the carpet. The washing and the rinsing apparatus being located close to the supporting and rinsing rolls the jets are pointed at the carpet conveyed between the rolls. The carpet is in a bent position, whereby the gaps between the fibres are opened and a good cleaning effect is achieved. In addition comes, that the device in accordance with the invention is simple to manufacture and to operate.
In the following the invention is explained in detail by referring to the attached drawings, which illustrate a device in one application of the invention.
