Definitions

  • the present invention relates to a washing machine comprising a dispenser wherein the cleaning agents are loaded.
  • Washing machines comprise a dispenser having more than one compartment wherein the cleaning agents are loaded.
  • the powder and liquid cleaning agents are loaded into separate compartments from each other and are transferred to the drum by being mixed with the water taken from the mains during washing.
  • the powder cleaning agents are transferred to the drum by passing through the opening situated behind the compartment after being mixed with the water taken into the compartment.
  • the liquid cleaning agents are preferred to be transferred to the drum by means of siphoning since they, due the their fluid feature, pass directly to the line connected to the drum as soon as they are loaded into the dispenser. Therefore, the rear wall of the compartment wherein the liquid cleaning agents are loaded is closed and the liquid cleaning agent is transferred to the drum by means of a siphon providing the cleaning agent to be discharged together with water when the water filled therein reaches a certain level.
  • the passage of the water taken from the mains during the washing is provided by means of the flushing device disposed on the dispenser.
  • the flow rate of the water supplied into the dispenser by means of the flushing device is determined to be enough for effectively sweeping all cleaning agents, mainly the powder cleaning agents.
  • high-flow rate water is supplied into the compartment wherein the liquid cleaning agents are disposed or when the mains pressure is high, the liquid cleaning agent in the compartment is agitated and hence tends to foam.
  • foaming occurs in the compartment wherein the liquid cleaning agents are loaded, the foams that occur pass towards the orifice of the siphon pipe during the transfer of the liquid cleaning agent to the drum by being siphoned and clog the siphon pipe. In this situation, the siphoning of the liquid cleaning agent is interrupted and the desired amount of liquid cleaning agent cannot be transferred to the tub by being siphoned. Therefore, degradations occur in the washing performance.
  • the aim of the present invention is the realization of a washing machine wherein the whole liquid cleaning agent loaded into the dispenser is provided to be effectively transferred to the drum.
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a dispenser having at least one compartment wherein the liquid cleaning agents are loaded and a siphon that is situated in the compartment, that provides the liquid cleaning agent to be transferred to the drum by being sucked together with the water when the water taken into the compartment reaches a certain level and that has a siphon pipe and the siphon lid inserted onto the siphon pipe.
  • the washing machine furthermore comprises a defoaming means which is held in a suspended position over the compartment and which extinguishes the foams in the compartment during the siphoning of the liquid mixture in the compartment. Thus, foam is prevented from entering between the siphon pipe and the siphon lid.
  • the whole liquid cleaning agent in the compartment is provided to be transferred into the drum by being sucked into the siphon pipe without any problem by preventing air bubbles from entering between the siphon pipe and the siphon lid.
  • the compartment is configured as a chamber independent of the dispenser.
  • the compartment is placed in the dispenser by loading liquid cleaning agent into the compartment.
  • the liquid cleaning agent is provided to be loaded into the compartment more easily.
  • the base of the compartment is in inclined form.
  • some of the foams in the compartment is dampened by itself by impacting the higher portion of the inclination of the base of the compartment.
  • the defoaming means is produced to be one-piece with the siphon lid.
  • the defoaming means which is connected to the siphon lid, is held in a suspended position in the compartment.
  • the defoaming means is configured so as to be detachably mounted to the compartment.
  • the defoaming means cleaning process is facilitated.
  • the defoaming means is hung on two opposite side walls of the compartment.
  • the defoaming means remains at a suspended position over the compartment by being mounted on the siphon lid.
  • the capability of the defoaming means to prevent air bubbles from entering into the siphon pipe is improved and the process of siphoning the liquid mixture in the compartment is made more effective.
  • air bubbles are prevented from entering between the siphon pipe and the siphon lid by dampening the foams in the compartment by means of the defoaming means during the transfer of the liquid cleaning agent to the drum.
  • the whole liquid detergent agent is transferred into the drum and hence, the cleaning efficiency of the washing machine is increased.
  • Figure 1 – is the schematic view of a washing machine.
  • Figure 2 – is the perspective view of a dispenser and a defoaming means related to an embodiment of the present invention.
  • Figure 3 — is the cross-sectional view of the dispenser and the defoaming means related to an embodiment of the present invention.

  • the washing machine (1) comprises
  • the washing machine (1) of the present invention furthermore comprises a perforated defoaming means (8) which is held at a suspended position over the compartment (4) and which provides the foams that occur in the compartment (4) to be dampened by impacting.
  • the defoaming means (8) is positioned at a certain height from the base of the compartment (4).
  • the air bubbles which move downwards together with the liquid level that decreases as the liquid mixture in the compartment (4) is sucked into the siphon pipe (6), burst by impacting the defoaming means (8) and vanish by being dampened.
  • the air bubbles are prevented from entering between the siphon pipe (6) and the siphon lid (7). Consequently, the problem of vacuum occurring that is caused by the air bubbles that can enter between the siphon pipe (6) and the siphon lid (7) is prevented. Since the occurrence of vacuum between the siphon pipe (6) and the siphon lid (7) prevents the sucking of the liquid mixture in the compartment (4), the whole liquid mixture in the compartment (4) is provided to be effectively sucked by means of the defoaming means (8). Thus, the siphon effect is prevented from being adversely affected while the liquid cleaning agent loaded into the compartment (4) is transferred to the drum (2).
  • the washing performance of the washing machine (1) is improved by transferring the whole liquid cleaning agent in the compartment (4) to the drum (2).
  • the compartment (4) is of detachable configuration.
  • the user loads the liquid cleaning agent outside the dispenser (3), independently of the dispenser (3) and places the compartment (4) into the dispenser (3).
  • the process of loading of the liquid cleaning agent by the user is facilitated.
  • the base of the compartment (4) is in inclined form.
  • some of the air bubbles, which form in the compartment (4) as the level of the liquid cleaning agent-water mixture decreases, is provided to be dampened by impacting the base of the compartment (4).
  • the defoaming means (8) is integrated with the compartment (4).
  • the production of the defoaming means (8) is facilitated.
  • the defoaming means (8) is integrated with the siphon lid (7).
  • the defoaming means (8) is held at a suspended position in the compartment (4).
  • the defoaming means (8) is enabled to be mounted and dismounted together with the siphon lid (7).
  • the defoaming means (8) is of detachable configuration.
  • the defoaming means (8) is provided to be dismounted and cleaned by the user and again mounted in place.
  • the defoaming means (8) is mounted to the side wall of the compartment (4).
  • the process of mounting and dismounting the defoaming means (8) is facilitated.
  • the defoaming means (8) is mounted on the siphon lid (7).
  • the defoaming means (8) is hung on the siphon lid (7) by passing the opening, which is located on the defoaming means (8) and the width of which is almost equal to the width of the siphon lid (7), over the siphon lid (7).
  • Stoppers which provide the defoaming means (8) to remain in the fixed position and prevent the defoaming means (8) from sliding downwards, are disposed on the siphon lid (7).
  • the whole liquid cleaning agent is provided to be transferred to the drum (2) by preventing the occurrence of problems in the siphoning process during the transfer of the liquid cleaning agent into the drum (2).
  • the washing performance of the laundry is improved.
