Definitions

  • the present invention relates to a dishwasher which provides intensive washing.
  • the water is enabled to be delivered to the washing tub in a more scattered manner.
  • the use of the secondary spray arms also ensures intensive washing.
  • the dirt level and dimensions of the kitchen items placed in every part of the washing tub are not the same. Therefore, certain areas require more intensive washing in some washing processes.
  • intensive washing zones are additionally used in the state of the art.
  • said additional washing systems increase the cost and the same type of kitchen items must always be positioned in the same place in order to ensure efficiency.
  • the aim of the present invention is the realization of a dishwasher which increases the washing performance and which provides ease of production.
  • 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 body; a washing tub which is disposed in the body; a sump which is disposed under the washing tub; at least one spraying member which delivers the water into the washing tub; a multiport valve which is disposed in the sump and which delivers the water to the spraying member; a delivery line which is disposed between the multiport valve and the spraying member; and at least one secondary spray arm which is disposed on the spraying member.
  • the spraying member rotates around its own axis under the effect of water coming from the delivery line.
  • the water delivered to the spraying member is delivered to the secondary spray arms such that the secondary spray arms are also enabled to rotate around their own axes.
  • the water can be delivered into the washing tub in various directions.
  • the water collected in the sump (4) is delivered to the spraying members (5) by means of the multiport valve (6) and the connected delivery line (7).
  • the multiport valve (6) which operates as a shutter system, enables the water to be delivered to areas such as the lower spraying member (5), the upper spraying member (5), the top washing or the intensive washing.
  • the secondary spray arms (8) provided on the spraying member (5) can rotate around their own axes under the influence of water. By means of the rotation of the spraying member (5) around its own axis and the rotation of the secondary spray arms (8) around their own axes, the water is delivered in various configurations in the washing tub (3), providing homogeneous washing.
  • the dishwasher (1) of the present invention comprises a stopping member (9) which is disposed on the delivery line (7) so as to be under the spraying member (5) and which has an open position where the stopping member (9) prevents the spraying member (5) from moving around its own axis by moving depending on the pressure of the water coming from the delivery line (7), and a closed position where the stopping member (9) does not come into contact with the spraying member (5).
  • the stopping member (9) moves vertically upwards and shifts to the open position.
  • the stopping member (9) is in the open position, the rotation of the spraying member (5) around its own axis is stopped.
  • the secondary spray arms (8) rotate around their own axes under the effect of the incoming water.
  • Various washing areas are established by means of the secondary spray arms (8) being able to rotate in a fixed area in the washing tub (3).
  • the washing tub (3) is provided with various intensive washing areas.
  • the dishwasher (1) comprises a plurality of openings which are arranged almost peripherally on the housing (10).
  • the housing (10) having the peripherally-arranged openings (16) close to the bottom, the movement of the piston (11) is prevented from moving due to possible water leaks.
  • the piston (11) is shifted between the open position and the closed position in a controlled manner.
  • the dishwasher (1) comprises a protrusion (16) which is provided on the second surface (14) and which bears against the edge of the hole (12) when the stopping member (9) is in the open position so as to prevent the piston (11) from moving further.
  • the peripheral protrusion (16) provided on the second surface (14) bears against the edge of the hole (12).
  • the dishwasher (1) comprises the stopping member (9) which, when in the open position, ensures that the water coming from the delivery line (7) pushes the first surface (13) such that the piston (11) moves upwards in the vertical plane and comes out of the hole (12) and stops the spraying member (5) and which, when in the closed position, ensures that the piston (11) remains completely in the housing (10) such that the movement of the spraying member (5) is not blocked.
  • the stopping member (9) When the stopping member (9) is in the open position, the water coming from the delivery line (7) pushes the first surface (13) and the second surface (14) such that the piston (11) moves upwards in the vertical plane.
  • the piston (11) contacts the spraying member (5) and prevents the same from rotating around its own axis, enabling only the secondary spray arms (8) to rotate.
  • the rotating secondary spray arms (8) establish fixed intensive washing areas.
  • a dishwasher (1) is realized, wherein the stopping of the spraying member (5) is controlled by means of a stopping member (9) which can shift between the open position and the closed position with the effect of water pressure. Intensive washing areas are established by means of the secondary spray arms (8) disposed on the stopped spraying member (5). When the spraying member (5) rotates around its own axis, homogeneous washing is provided.
