Definitions

  • the present invention relates to a method for washing laundry according to the preamble of independent patent claim 1, and to a continuous washing machine according to the preamble of independent patent claim 5.
  • Continuous washing machines are known; such is described in DE-A-29 49 228.
  • This washing machine has a washing tube which can be rotated about its longitudinal axis.
  • washing chambers are separated, which are separated from each other in terms of bath during the washing process.
  • the chambers are connected to lines which can be shut off by valves in such a way that a counterflow of liquid is achieved for the movement of the waxes. Due to the possibility of not only feeding this countercurrent into the chamber just preceding, but also of skipping individual ones, different laundry items can be washed in batches.
  • Such a washing machine requires ten compartments for washing, namely two for the soaking zone, for example five washing compartments assigned to the washing zones and three compartments for carrying out three wash cycles.
  • a reduction in the number of compartments is possible with the continuous washing machine according to DE-A-29 00 467, namely two compartments for the prewash or soaking zone, three compartments for the washing zone and two for the rinsing zone, one of which is intended as a finishing zone; thus a maximum of eight compartments are necessary, and if the finishing which is not necessary for every wash is carried out outside the wash tube, seven compartments are sufficient for this washing machine.
  • the fleet is specifically adjusted to the respective needs by pumping the liquid and either directing it into an intermediate container or directly into the subsequent chamber. This means that the fleet can be used several times with the same type of laundry and can be cached with different laundry. Because this can only be achieved with a double drum machine, in which each chamber is provided in its own housing with its own drive for the chamber, the effort in material and labor for assembling such a continuous washing machine is great.
  • the continuous washing machine according to FIG. 1 consists of five chambers K1-K5 combined to form a tube, of which the two outer chambers K1 and K5 are provided with an input funnel E or with an output chute AG. These two chambers K1 and K5 also have a greater axial length than the other chambers K2-K4.
  • the chamber K1 because the dry, airy clenched laundry takes up more space than the wet heavier laundry, and the chamber K5 because the level must be kept lower because of the discharge chute AG than for the other washing processes, so that the same liquor ratio is also in the chamber K5 as is made possible in chambers K2 to K4.
  • the chamber K1 is the prewash stage
  • the chambers K2 and K3 form the final wash stage
  • the chambers K4 and K5 represent the rinse stage.
  • the two chambers K2 and K3 are equipped with thermal insulation materials so that the heat loss emitted to the environment can be kept as low as possible.
  • the wastewater from the four rinse cycles is intended to be reused without increasing the energy required but rather saving it.
  • the usual water requirement can be reduced from 301 water per kg of dry laundry to around 101 and the energy requirement can be reduced to half of the otherwise required energy by utilizing the heat in the recovered water.
  • the chambers K2, K4 and K5 each have a lock with supply lines K2E, K4E and K5E and exit lines K2W, K4W and K5W for the supply and removal of the necessary liquids in addition to the heat supply.
  • the feed line K1 E to the filling funnel E effects the washing in of the dry laundry and at the same time the soaking.
  • the last rinse water from chamber K5 as splash water SW reaches the laundry in a dewatering device (not shown), which can be a centrifuge or a press.
  • the control for assigning the rinse water to the tanks A, B, C or the routing of the prewash water VW and the clear wash water KW is controlled by valves V1-V5, and the liquids are supplied to the chambers K2, K4 and K5 including the filling funnel the pumps P1-P3 and a valve V6, which is connected to the fresh water line Z.
  • the fresh water line Z is connected to all three tanks A, B, C via valves VZ, which are not individually identified, and a waste water line AW is accordingly fed with valves VA from tanks A, B, C and also receives the waste water from the chambers K2 and K4 Valves V1 and V2 with lines L8 and L11.
  • the first rinse water Sp1 from the previous wash cycle is located in the tank A, the remaining tanks B and C are empty except for residual water.
  • the laundry was carried from each chamber to the next stage.
  • the prewashed laundry with the prewash liquor VW is thus in the chamber K2 and the clearwashed laundry in the rinse wash liquor KW is in the chamber K4.
  • the valves V1 and V2 are opened so that the pre-wash liquor VW can reach the drain via the lines L5 and L8 from the lock exit K2W and the clear wash liquor KW can reach the drain via the lines L6 and L11.
  • the valve V4 was previously opened in order to introduce the second rinse water Sp2 from the lock exit K4W via the lines L6 and L9 into the container A. With pump P1, this flushing water Sp2 is fed via line L1 to the flushing inlet K1E in the filling funnel E.
  • the container B with the first rinse water Sp1 of the previous cycle and the container C with the surge water SW are now filled.
  • valves V1, V2 are thus closed and the pump P1 is switched off.
  • the pumps P2 and P3 are also switched on and the valve V6 is opened.
  • the first flushing water Sp1 of the previous cycle is thus removed from the container B via the line L2 and the inlet line K2E to the chamber K2
  • the pump P3 feeds the water from the container C into the chamber K4 as the first rinse water Sp1 via the line L3 and fresh water from the line Z is fed to the chamber via the line L4 with the valve V6 K5 fed as third rinse water Sp3.
  • valves V3 for draining the first rinsing water Sp1 into the container A and V5 for draining the third rinsing water Sp3 into the container C are opened at time 4 '.
  • the pump P3 is switched on in order to supply the water from the container C via the line L3 as the second rinse water Sp2 to the chamber K4.
  • fresh water is discharged from the line via the valve V6 and the line L4 Z is fed as fourth rinse water Sp4 into the chamber K4.
  • the wash cycle has ended at time 8 '.
  • the tube was swung back and forth to wash the laundry in a known manner. So that the water levels in the individual chambers K1, K2, K4 and K5 are adapted to the respective requirements, the pump P1 is timed, and the pumps P2, P3 and the valve V6 are controlled by level switches by the levels in the associated chambers K2, K4 and K5 controlled.
  • the laundry is heated to this 40 ° in the prewash cycle. As is known, this temperature must not be exceeded due to protein fixation.
  • the 60 ° warm first rinsing water S p 1 is used for clear washing, so that a mixing temperature of about 50 ° arises, which must now be heated to the clear washing temperature.
  • This intersecting use of the first and second rinse water Sp1 and Sp2 enables the above-mentioned short clear wash time of 16 minutes and next to the Einspa Water consumption of around 66% can save heat energy of around 50% and in addition there is a cycle time of 40 minutes for washing.
  • the tube with the chambers K1-K5 is arranged above the containers A, B, C and is supported on a frame R in a rolling manner in a known manner.
  • the drive motor M with gear and friction rollers or gear connection to the tube.
  • the frame supports RS shown serve for fastening cover plates, of which a cover plate P can be seen behind the pipe. The front ones are removed accordingly.
  • this washing machine in the washroom it is therefore sufficient for this washing machine in the washroom to provide a drainage channel for the liquids to be removed from prewash water VW, clear wash water KW and cleaning water RW from the waste water line A, a connection for the fresh water supply Z and a device for heating the liquor in the chamber K4.
  • An example embodiment for an hourly laundry cycle of 150-300 kg has a length of around 3.5 m with an installation height of just over 2.5 m.
