Definitions

  • the present invention relates to a dishwasher with improved washing performance.
  • Dishwashers generally comprise upper and lower racks which are placed into the washing tub and where kitchen items, pots and pans and dishes are placed, loaded or taken out of the dishwasher.
  • a spray arm connected to the water line, which rotates and sprays water onto the items placed on the rack.
  • the state of the art dishwasher comprises, in addition to the existing spray arm, additional, auxiliary spray arm which enable extra water to be sprayed in the area where the items with relatively heavy dirt are placed. Thus, the items with heavy dirt are cleaned more effectively.
  • the auxiliary spray arms cannot spray water adequately to the desired area.
  • the design of water transfer and spraying becomes complicated and the production and installation costs increase.
  • a dishwasher having a nozzle which extends from the side of the spray arm and which sprays water to a region of the rack.
  • a dishwasher comprising a bar-shaped pipe having nozzles thereon, which is disposed under the rack in addition to the spray arm, which controls the flow of water by means of various valves and which enables the water to be sprayed intensely to a region.
  • a dishwasher comprising channels having nozzles thereon at certain intervals, which extend from back to front parallel to the side wall of the dishwasher in addition to the spray arms.
  • the aim of the present invention is the realization of a dishwasher with improved washing performance.
  • the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a washing tub which has two side walls and a rear wall; a door which provides access to the washing tub from outside; at least one rack which is positioned in the washing tub and which has a loading position wherein the items are loaded thereon while at least partially outside the washing tub and a washing position wherein the rack is completely in the washing tub; a cylindrical pipe which is closed at one end, which is attached to the rack, which has an inlet connected to the water line when the rack is in the washing position and through which the water flows; at least one passage which is provided on the wall of the pipe; and at least one spraying member which is in the form of a hollow ring, which is borne on the pipe by surrounding the passage all around, which moves radially around the axis where the spraying member is borne on the pipe and which has at least one outlet on the outer wall thereof, extending in a direction perpendicular to the axis where the spraying member is borne.
  • the spraying members rotate around the axis where the same are borne on the pipe with the pressure of the water.
  • the rotation speed of the spraying member varies according to the water pressure.
  • the horizontal axis of the pipe and the rotation axis of the ring overlap.
  • the number of passages in the pipe wall is two and these passages are located on the same diameter.
  • the spraying member comprises two outlets which are arranged on the same diameter, but open to opposite directions and which are perpendicular to the horizontal axis of the pipe. In another embodiment, there is 180° between the two outlets on the spraying member.
  • the spraying member comprises at least one spray nozzle which is provided above the outlet and which enables the water flowing in the pipe and passing through the passage to be sprayed.
  • the spray nozzle forms a protrusion extending outwards on the outer wall of the spraying member, and the outlet is positioned in a direction perpendicular to the horizontal axis of the pipe.
  • the spray nozzles are disposed on the same line passing through the center of the spraying member, there is 180° therebetween, and the outlets face opposite directions.
  • the water entering the spraying member is directed to the outlets from the spray nozzles and at the same time, enables the spraying member to rotate around its own axis like a wheel such that water is effectively sprayed into the washing tub.
  • the dishwasher comprises the pipe which extends along the bottom of the rack and at least two spraying members which are arranged at certain intervals on the pipe. In the preferred embodiment of the present invention, there are thirteen spraying members.
  • the dishwasher comprises at least one hanging means which is bent in the form of a C, which is provided on the pipe and which enables the pipe to be attached to the rack.
  • the hanging means is attached to the wires forming the rack and remains stable and fixed at the base of the rack.
  • the hanging means is disposed between two spraying members.
  • the dishwasher comprises two pairs of hanging means between the spraying members on a pipe.
  • the pipe is L-shaped.
  • the spraying members are positioned on the pipe along the long side of the pipe.
  • the straight form and the L form of the pipe are used together.
  • the door in order to load the items to be washed into the rack, the door is opened and the rack is partially or completely pulled out of the washing tub.
  • the rack changed to the loading position is pushed in the opposite direction after loading the items to be washed therein and thus the rack is placed into the washing tub.
  • the pipe is physically connected to the water line.
  • water preferably pressurized
  • the pressurized water transmitted from the water line to the pipe enters the spraying members through the passages while moving through the pipe and the water is enabled to be sprayed through the outlets in the spray nozzles into the washing tub and hence towards the rack to which the pipe is attached.
  • the spraying members rotate around the axis where the same are borne on the pipe.
  • the area in the rack where the items with heavy dirt are placed is cleaned more effectively.
  • the spraying member moves radially around the axis where the same is borne on the pipe and sweeps the area in the rack where the pipe is attached with water.
  • the washing performance of the dishwasher is increased and by enabling regional washing, higher washing performance is achieved with lower energy consumption values.
  • the dishwasher (1) comprises a washing tub (2) which has two side walls and a rear wall; a door (3) which provides access to the washing tub (2) from outside; at least one rack (4) which is positioned in the washing tub (2) and which has a loading position wherein the items are loaded thereon while at least partially outside the washing tub (2) and a washing position wherein the rack (4) is completely in the washing tub 82); a cylindrical pipe (6) which is closed at one end, which is attached to the rack (4), which has an inlet (11) connected to the water line (5) when the rack (4) is in the washing position and through which the water flows; at least one passage (9) which is provided on the wall of the pipe (6); and at least one spraying member (7) which is in the form of a hollow ring, which is borne on the pipe (6) by surrounding the passage (9) all around, which moves radially around the axis where the spraying member (7) is borne on the pipe (6) and which has at least one outlet (10) on the outer wall thereof, extending in a direction perpendicular
  • the spraying members (7) rotate around the axis where the same are borne on the pipe (6) with the pressure of the water.
  • the rotation speed of the spraying member (7) varies according to the water pressure ( Figure 1 and Figure 2 ).
  • the horizontal axis of the pipe (6) and the rotation axis of the spraying member (7) overlap.
  • the number of passages (9) in the pipe (6) wall is two and these passages (9) are located on the same diameter.
