  • the laundry washing/drying system realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, a washing machine and a drying machine which are connected to each other by means of a delivery line; and a water delivery member having a casing, a condensate inlet pipe connected to the delivery line which transfers the condensate stored in the collection tank in the drying machine to the washing machine, a mains water inlet pipe connected to a mains line where the mains water taken from the mains to the washing machine is carried, a mains water drive wheel which rotates with the effect of the mains water coming from the mains line hitting a plurality of first blades thereon, a shaft that determines the rotational axis of the mains water drive wheel and rotates around its own axis together with the mains water drive wheel, a condensate drive wheel which is located on the same shaft, whereon a plurality of second blades are provided and which rotates with the shaft so as to push the condensate coming from the delivery
  • the water in the collection tank is enabled to be delivered to the washing machine without consuming electrical energy and to be used as washing water. Consequently, it is ensured that the washing machine draws less water from the mains and both energy and water consumption of the laundry washing/drying system is reduced.
  • the water delivery member has a mains water receptacle which is filled with the mains water coming from the mains line, a condensate receptacle which is filled with the condensate coming from the delivery line, a first discharge pipe through which the mains water exits the mains water receptacle to be sent to the tub, and a second discharge pipe through which the condensate exits the condensate receptacle to be sent to the tub.
  • the laundry washing/drying system comprises an inner wall which is provided in the casing, which isolates the condensate receptacle and the mains water receptacle from each other without any water communication and which is disposed between the receptacles, a shaft opening on which is arranged on the inner wall and which enables the shaft to extend through the receptacles and provide motion transmission, and a sealing member which is positioned between the shaft and the shaft opening.
  • the water delivery member comprises the mains water inlet pipe, the condensate inlet pipe, the first discharge pipe through which the mains water is sent to the tub and the second discharge pipe through which the condensate is sent to the tub, and the first discharge pipe and the second discharge pipe have different diameters from each other.
  • the water flow rate in the pipes can be controlled only by mechanically changing the diameter values of the pipes.
  • the first blade and the second blade have a helix form.
  • the helix geometry increases the driving power of the water and reduces the noise generated during the water delivery.
  • the mains water drive wheel and the condensate drive wheel have different diameters and different numbers of blades.

  • the condensate stored in the collection tank in the drying machine is transferred to the tub in the washing machine without the need for using a pump.
  • the laundry washing/drying system (1) comprises a drying machine (4) having a condenser which dehumidifies the drying air and a collection tank (3) wherein the condensate formed in the condenser (2) is collected; a washing machine (7) having a tub (5) wherein the washing process is performed, a mains line (6) through which the mains water is taken and at least one feeding line (22) which carries the water to be delivered to the tub (5); and a delivery line (8) which enables the condensate in the collection tank (3) to be delivered to the washing machine (7).
  • the laundry washing/drying system (1) of the present invention comprises a water delivery member (15) having a casing (9), a mains water inlet pipe (10) which is provided on the casing (9) and through which the mains water coming from the mains line (6) enters, a condensate inlet pipe (11) which is provided on the casing (9) and through which the condensate coming from the delivery line (8) enters, at least one discharge pipe (17, 18) which is provided on the casing (9) and which is connected to the feeding line (22), a mains water drive wheel (14) which is connected to a shaft (12), which has a plurality of blades (13) thereon and which rotates together with the shaft (12) as the water coming from mains line (6) hits the first blades (13), and a condensate drive wheel (15) which is connected to the shaft (12), which has a plurality of second blades (113) thereon, which rotates with the rotational movement of the shaft (12) so as to move the condensate coming from the delivery line (8)

  • the mains water inlet pipe (10) is provided such that the water coming from the mains line (6) can enter the casing (9).
  • the condensate inlet pipe (11) is provided, through which the condensate from the transmission line (8) stored in the collection tank (3) and used for washing the laundry in the tub (5) can enter. Pressurized water passing through the mains water inlet pipe (10) hits the first blade (13) on the mains water drive wheel (14) and rotates the shaft (12) on its own axis, whereon the first blade (13) is located.
  • the condensate coming from the delivery line (8) is stationary with the effect of gravity.
  • the dynamic pressure of the condensate accumulated in the second blade (113) on the condensate drive wheel (114) is increased with the rotational movement of the shaft (12).
  • the dynamic pressure of the condensate coming from the collection tank (3) with the effect of gravity is increased without using a pump.
  • the water delivery member (15) has a mains water receptacle (16) which is provided in the casing (9) and which is filled with the mains water coming from the mains line (6), and a condensate receptacle (116) which is provided in the casing (9) and which is filled with the condensate coming from the delivery line (8).
  • the mains water and the condensate are filled into separate receptacles so as to prevent them from mixing with each other.
  • it is aimed to prevent the reduction of the rotational speed of the shaft (12) and thus the driving power of the water delivery member (15) due to the collection of the high-pressure mains water in the same receptacle with the low-pressure condensate.
  • the water delivery member (15) has a first discharge pipe (17) through which the mains water filling the mains water receptacle (16) exits the casing (9) and a second discharge pipe (18) through which the condensate filling the condensate receptacle (116) exits the casing (9). It is provided that the condensate and the mains water exit the water delivery member (15) through separate pipes.
  • the diameter values of the first discharge pipe (17) and the second discharge pipe (18) can be changed so as to adjust the dynamic pressures thereof, and pressure loss which would occur in the case an outlet pipe is used is prevented.
  • a shaft opening (20) which allows the shaft to pass therethrough and extend from the mains water receptacle (16) to the condensate receptacle (116).
  • the rotational movement of the mains water drive wheel (14) and the shaft (12) around its own axis is transferred to the condensate drive wheel (114) located in the condensate receptacle (116).
  • At least one sealing member (21) is placed between the shaft opening (20) and the shaft (12).
  • the pressure in the mains water is used to send the condensate to the tub (5) at the optimum level.
  • the condensate inlet pipe (11) has a larger diameter than the diameter of the second discharge pipe (18).
  • the smaller diameter of the second discharge pipe (18) causes the dynamic pressure of the condensate sent from the water delivery member (15) to the tub (5) to be increased, thus enabling the condensate to reach the tub (5) easily.
  • the first blade (13) and the second blade (113) have a curved form.
  • the curved blade structure increases the water drive power and reduces the noise generated by the water hitting the blades (13, 113).
  • the angles of the blades (13, 113) can be changed as desired so as to adjust the dynamic pressure values gained by the mains water and the condensate.
  • the transfer of the condensate stored in the drying machine (4) to the tub (5) in the washing machine (7) is provided in a cost-effective manner without using any pump.
