Definitions

  • the present invention relates to a washing machine that comprises a washing agent dispenser.
  • washing agent dispenser In washing machines, e.g. in clothes or dish washing machines, the washing agent required for the cleaning process is emplaced in a washing agent dispenser.
  • the washing water taken in from the water inlet and heated if required is directed into the washing agent dispenser.
  • the dissolved-melted washing agent passes into the washing tub together with water.
  • the washing agent dispenser frequently includes compartments wherein the powder and/or liquid washing agents are emplaced.
  • the washing agent dispenser comprises at least one compartment wherein the liquid washing agent (e.g. softener) is emplaced.
  • the liquid washing agent e.g. softener
  • the hole has to be positioned at a point above the level of the softener. This necessitates additional arrangements for conveying the softener up to the hole above at the time required by the washing program.
  • the softener In state-of-the-art washing agent dispensers, the softener is sucked into the hole by the siphon effect and is transferred to the tub therefrom.
  • a cylinder is provided that rises up from the base of the compartment, with its lower end extending into the washing tub, the upper end extending into the compartment.
  • a concentric cartridge with a wider diameter is fitted over this cylinder such that the upper end is not covered.
  • the lower side of the cartridge is higher than the base of the compartment. Accordingly, the liquid washing agent emplaced in the compartment still communicates with the cylinder inside the cartridge.
  • a hole is positioned below the liquid washing agent level in the liquid washing agent (e.g. rinsing aid) compartment and this hole is controlled by a valve by opening or closing.
  • the liquid washing agent e.g. rinsing aid
  • the object of the present invention is the realization of a washing machine comprising a washing agent dispenser that provides a more effective use of the liquid washing agent contained therein.
  • the washing machine designed to fulfill the object of the present invention is explicated in the attached claims.
  • the washing agent dispenser used in the said washing machine at least one hole is provided on the base of the compartment that opens to the washing tub.
  • the liquid washing agent mass having a certain viscosity at a certain level does not flow down the hole since its surface tension in the vicinity of the hole balances the pressure at that depth due to the dimensions and shape of the hole.
  • the washing program goes on, water is taken into the compartment when the liquid washing agent has to be delivered to the tub.
  • washing machine comprising a washing agent dispenser is provided by taking advantage of the surface tension without necessitating the use of any siphon devices or valves.
  • the production of the said washing agent dispenser is easy, has a low cost since it comprises holes only on its base.
  • Figure 1 - is the schematic view of a washing machine.
  • Figure 2 - is the schematic view of a washing agent dispenser.
  • Figure 3 - is the top view of a washing agent dispenser in an embodiment of the present invention.
  • FIG. 4 - is the detailed perspective view of a washing agent dispenser in an embodiment of the present invention.
  • the washing machine (1) is utilized for the cleaning of the items like dishes and laundry by means of washing with water.
  • the washing machine (1) of the present invention comprises,
  • the washing agent dispenser (3) comprises holes (5) disposed on the base of the compartment (4).
  • Each hole (5) is sized such that the pressure of the washing agent having a certain depth (h) and a certain viscosity at the level of the hole (5) is enough to balance its surface tension over the hole (5) ( Figure 3 and figure 4 ). Accordingly, when poured into the compartment (4) up to the maximum level determined by the producer, the liquid washing agent does not flow down the holes (5).
  • the water inlet (6) is opened, water starts to be taken into the compartment (4), the pressure of the water-liquid washing agent mixture at the level of the hole (5) overcomes its surface tension over the hole (5), and it starts flowing down the holes (5) into the tub (2).
  • the producer determines the maximum amount of liquid washing agent to be poured into the compartment (4) and designs the size and shape of the holes (5) such that this amount of liquid washing agent does not flow into the tub (2) at an undesired time.
  • the user pours in the required amount of liquid washing agent into the compartment (4) suitable for the selected washing program. While the washing program goes on, the water inlet (6) is opened when the time comes for the step of taking in the liquid washing agent. The water starting to fill in the compartment (4) begins mixing with the washing agent.
  • the density and the viscosity of the liquid washing agent starts to decrease, when its pressure on the base of the compartment (4) gets higher than its surface tension on the hole (5), the water- liquid washing agent mixture starts flowing down the holes (5) towards the tub (2). It is possible to deliver the entire liquid washing agent into the tub (2) since the holes (5) are arranged on the base of the compartment (4).
  • the entire base of the compartment (4) is perforated with holes (5).
  • the holes (5) are clustered in a certain region on the base of the compartment (4) ( Figure 3 and Figure 4 ).
  • the hole (5) cluster preferably is arranged on the rear side of the compartment (4).
  • the hole (5) cluster is situated preferably on a recessed in area on the base of the compartment (4). Accordingly, as much of the washing agent as possible poured in to the compartment (4) reaches the holes (5) and is discharged from the holes (5).
  • the base of the compartment (4) is inclined, and the dimensions of the holes (5) change depending on the depth of the compartment (4). Since the pressure of the washing agent is more in the deeper region, the dimensions of the holes (5) here are smaller. By way of the slope, the liquid washing agent is provided to flow better after the surface tension is overcome.
  • the viscosity of the liquid washing agents used is around 0.8-1.3 cs. It is observed that a softener having this viscosity poured to a level of 2-3 cm over a hole (5) having a diameter of 0.1-0.3 cm. does not flow down from the hole (4). However, when about 2-3 cm. height of water is added over the softener, it is observed that the surface tension at the hole (5) is overcome and the water-liquid washing agent mixture starts flowing down the holes (5). It is also possible to use these holes (5) together with a siphon arrangement.
  • a washing agent dispenser (3) that does not require a complex arrangement such as a siphon in the compartment (4) into which the washing agent is put. Since the said washing agent dispenser (3) has a simple configuration comprising holes (5) only on its base, its production is easy and has a low cost.
