  • the receptacle where the detergent is placed is fixed and the detergent falls into the machine thanks to the bevel in the detergent receptacle.
  • Detergent tablet does not fall into the same place every time; it may sometimes fall into a pot or glass.
  • the washing performance and efficiency of the machine decrease because detergent tablet falling into an unsuitable place is not mixed with the pressure water provided by spray arm or does not diffuse in the machine.
  • a spot has been created for the tablet falling from the detergent dispenser in the front rack of the dishwasher in some of the detergent dispenser models.
  • the tablet falls into the same place every time.
  • the tablet does not have the risk of falling into the pot or an unsuitable place; however, said embodiment has decreased the volume of upper rack.
  • the present invention is related to detergent dispenser meeting the abovementioned requirements, eliminating all of the disadvantages and offering some additional advantages.
  • the primary object of the present invention is to keep the detergent in a mobile detergent bed during the washing process and to flow the detergent melted with the water sprayed in the machine, into the machine.
  • Another object of the present invention is to eliminate the problem of decrease in the washing performance arising from the fact that detergent tablet falls into unsuitable places within the machine.
  • the present invention is a detergent dispenser which is positioned within the dishwasher and comprises a detergent bed in which the detergent is positioned, and a cover that closes the detergent bed and provides sealing, characterized in comprising the following in order to provide the motion of said detergent bed on vertical axis;
  • the present invention is related to improvements made in the detergent dispenser of dishwashers, which is mounted at the back of front door (B) in the dishwashers (A).
  • a three-dimensional view of the detergent dispenser (1) comprising said improvements is given in Figure 1 .
  • detergent dispenser (1) mainly consists of a detergent bed (3), rinse aid receptacle (2) and motion mechanism provided within an outer body (10).
  • the detergent (C) and rinse aid agent, which help washing the dishes, are added into the detergent dispenser (1) by the user before the machine (A) starts to work.
  • the detergent bed (3) is designed in a mobile manner in the detergent dispenser (1) according to the present invention. While detergent bed (3) is closed in Figure 1 , it is opened in Figure 2 .
  • Detergent (C) that enables the dishes to be washed and is provided as tablet, liquid and powder is placed into the detergent bed (3).
  • Detergent flow channels (3.1) are provided in the form of openings on the body of detergent bed (3). As can be seen better in Figures 2 and 8 , detergent flow channels (3.1) are configured so as to enable the flow of detergent (C) melted while the machine (A) is working, into the machine (A) automatically.
  • a motion spring (7) and latch (5) are provided in the detergent dispenser (1) according to the present invention for the motion of detergent bed (3).
  • the motion spring (7) is a spring embedded horizontally within the outer body (10).
  • the latch (5) is a triggering member connected to the upper section of the detergent bed (3). While the detergent bed (3) is closed, a fixing lug (3.4) provided at the back of the detergent bed, and a latch lug (5.1) provided on the latch (5) are interlocked.
  • detergent bed (3) is fixed in closed position and remains in installed position after being compressed by the motion spring (7).
  • the side profile cross-sectional view of the detergent dispenser in a closed position is given in Figure 5 .
  • the interaction of spring bed (3.3) and motion spring (7) while the detergent bed (3) is in closed position, and positioning of latch lug (5.1) and fixing lug (3.4) are given in the side profile cross-section in Figure 5 .
  • detergent bed (3) is seen from side profile when it is opened in Figure 6 . While the detergent bed (3) is opened, the motion spring (7) is released and latch lug (5.1) and fixing lug (3.4) are separated from each other.
  • a mobile cover (4) that provides sealing for liquid and powder detergent when the detergent cover (3) is closed is provided at the lower section of the detergent bed (3).
  • the view of collapsible cover (4) is seen in a side profile cross-section received from the bottom of detergent dispenser (1) according to the present invention is seen in Figure 7 .

  • the cover (4) closes the bottom of the detergent bed (3) while the detergent bed (3) is closed ( Figure 1 ).
  • cover spring (4.1) is compressed and installed.
  • the cover (4) is closed automatically with the effect of compressed cover spring when the detergent bed (3) is pushed upwards (+y) by the user.
  • collapsible cover (4) is seen in a side cross-section received from the bottom of detergent dispenser (1) according to the present invention in Figure 7 .
  • a gasket (6) that provides the sealing of detergent bed (3) is provided on the cover (4).
  • the working principle of the detergent dispenser (1) is as follows: Before the dishwasher (A) is started, the front door (B) is opened and detergent tablet (C) is placed into the detergent bed (3) of the detergent dispenser (1) and rinse aid liquid is filled into the rinse aid receptacle (2).
  • the three-dimensional view of the detergent bed (3) in which detergent (C) is placed, is given in Figure 9 .
  • detergent bed (3) is closed by being pushed upwards (+y) by the user.
  • the spring protrusion (3.3) at the lower surface (3.5) of the bed fits into the opening where the motion spring (7) is provided, and compresses the motion spring (7).
  • the front door (B) of the dishwasher (A) is closed and the machine (A) is started after choosing the washing programs on the front board.
  • the machine (A) starts to work.
  • the heater is activated and circulation motor operates. Meanwhile, an actuator pushes the latch (5) forwards.
