Definitions

  • the present invention relates to a laundry washing/drying system comprising a first household appliance and a second household appliance which are connected to each other in fluid communication.
  • the first household appliance is a laundry dryer and the second household appliance is a washing machine.
  • Laundry dryers have a drum provided in the body. After the laundry to be dried is placed in the drum, the drying air is delivered into the drum. The hot and humid drying air drawn from the drum by a fan is directed to the condensation channel. The drying air is passed over a condenser provided in the condensation channel, thus cooling and dehumidifying the drying air. Water condensed from the moist air in the condenser is delivered to the tank by means of a pump and collected in the tank. A discharge outlet is provided on the tank, which allows the condensate collected in the tank to be discharged.
  • the condensate can be discharged directly by connecting the discharge outlet to the drain by means of a hose, or the discharge outlet can be deactivated such that the user is required to empty the tank at certain intervals.
  • the condensate generated in the laundry dryer is delivered to the washing machine as washing water through a discharge line and with the effect of gravity.
  • the effect of gravity ensures that the condensate is slowly delivered through the discharge line to a water inlet in the washing machine.
  • the slow delivery of the condensate containing small amounts of lint, etc. causes clogging in the water inlet and serious problems in washing performance. Therefore, there is a need for a laundry washing/drying system wherein the clogging problem occurring in the water inlet when the condensate is delivered to the washing machine by the effect of gravity is solved in a cost-efficient manner without using any pumps, etc.
  • EP2511413 discloses a laundry dryer which is placed on the washing machine and disclosed that the condensate generated in the laundry dryer is temporarily stored with the effect of gravity in a tank which is disposed in the washing machine.
  • the aim of the present invention is the realization of a laundry washing/drying system wherein the liquid flow rate from the first household appliance to the second household appliance is increased.
  • 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, comprises a first household appliance having a body, a drum which is disposed in the body and wherein the laundry to be dried is placed, a condenser which provides the dehumidification of the drying air, a tank which receives and collects the condensate formed in the condenser and a tank outlet which is provided on the tank and which enables the condensate collected in the tank to be discharged; a second household appliance having a tub wherein the washing process is performed, at least one water inlet through which the washing water is taken to be transferred to the tub, at least one valve which is provided on the water inlet, a control unit which controls the valve so as to adjust the amount of water to be taken into the tub; at least one discharge line which enables the condensate collected in the tank to be delivered from the tank outlet to the water inlet; and a connection member which is provided on the discharge line and which has at least one in
  • the flow rate of the water delivered to the water inlet is increased such that particles such as fluff, fiber, etc. accumulating at the water inlet are swept and delivered into the tub. Therefore, energy loss and decrease in washing performance caused by the clogging in the water inlet are prevented.
  • At least one second outlet port is provided on the connection member, and a second discharge line is connected to the second outlet port from one end and, from the other end, to at least one valve disposed on the body so as to interrupt the liquid flow out.
  • the valve is preferred to be placed on the upper part of the rear wall or on the side wall of the first household appliance.
  • the second discharge line is preferably manufactured from a flexible material.
  • the valve is configured to be opened and closed by the user so as to enable the water flow from the discharge line to the outside of the body to be interrupted.
  • a latch is provided, which enables the second discharge line to be separated from the valve when rotated around its own axis.
  • At least one holder is provided, which enables the second discharge line to be fixed on the body so as to allow the user to detach and attach the same from and to the body.
  • the holder preferably has a snap-fitting structure.
  • the second discharge line can be robustly fixed onto the body.
  • the discharge line has at least partially spiral form.
  • the condensate delivered from the discharge line to the water inlet creates a vortex, thus reducing the negative pressure which prevents the water from flowing.
  • the condensate is discharged much faster from the discharge line to the water inlet. Consequently, a cost-advantageous embodiment is realized wherein particles such as lint etc. accumulated in the water inlet or the discharge line is swept more effectively.
  • the opening on the discharge outlet is preferably circular and the barrier is almost semicircular.
  • the discharge outlet extends at angle with respect to the horizontal axis.
  • the opening is positioned at a higher level by extending the discharge outlet by a certain distance in the horizontal in an angled manner. Consequently, large amount of condensate is stored in the tank.
