  • the dispenser is enabled to be locked in a simple manner without the need for using an electronic equipment such as sensor, actuator, etc. and the safety of the washing machine is improved.
  • the first locking means is fixed to the dispenser at one end and, in the free position, extends just over the dispenser surface almost parallel to the movement direction of the dispenser.
  • a first locking means is provided on each of the left and right side of the dispenser, and the first locking means engage with the second locking means that are arranged on the housing in the locked position.
  • the dispenser is enabled to be locked firmly in a balanced manner on both sides.
  • cold water is supplied into the dispenser just after the hot water is supplied.
  • the first locking means is enabled to quickly switch from the locked position to the free position and the users are enabled to open the dispenser right after the supply of hot water.
  • the dispenser is enabled to be locked only when the hot water at high temperatures is being supplied, and the users are enabled to freely open the dispenser when there is not a supply of hot water or water at low temperatures is being supplied.
  • the safety of the washing machine is improved simply and effectively without limiting the user control.
  • Figure 1 - is the schematic view of the washing machine related to an embodiment of the present invention.
  • Figure 2 - is the sideways view of the dispenser and the first locking means related to an embodiment of the present invention.
  • Figure 3 - is the top view of the dispenser and the first locking means in the locked position related to another embodiment of the present invention.
  • Figure 4 - is an enlarged view of the detail X in Figure 3.
  • Figure 5 - is the top view of the dispenser and the first locking means in the free position related to another embodiment of the present invention.
  • the washing machine (1) comprises a body (2); a housing (3) arranged on the body (2); a dispenser (4) wherein the cleaning agents such as the detergent and the softener are loaded, that is movably placed into the housing (3) and that has an open position wherein the dispenser (4) extends outwards from the housing (3) and a closed position wherein the dispenser (4) is almost completely in the housing (3); a distributor (5) that enables water to be supplied into the dispenser (4), and at least one first locking means (6) and at least one second locking means (7) that are positioned respectively on the dispenser (4) and the housing (3) and configured to enable the dispenser (4) to be locked in the closed position by engaging with each other when the dispenser (4) is in the closed position.
  • the washing machine (1) of the present invention comprises the first locking means (6) that changes form based on the temperature and has a free position (A) wherein the first locking means (6) does not contact the second locking means (7) when the dispenser (4) is in the closed position and a locked position (B) wherein the first locking means (6) changes form with respect to the free position (A) due to the heat absorbed from the hot water when the hot water is supplied to the dispenser (4) through the distributor (5) and abuts the second locking means (7).
  • the first locking means (6) is produced from a shape memory material that changes form when the temperature thereof increases and returns to its original form when the temperature thereof returns to the first value.
  • the first locking means (6) When the hot water is not supplied into the dispenser (4), the first locking means (6) is in the free position (A) wherein the first locking means (6) is away from the second locking means (7), and allows the dispenser (4) to be moved in the housing (3).
  • the first locking means (6) heats up and changes form and thus, moves towards the second locking means (7) so as to shift to the locked position (B) and bear against the second locking means (7).
  • the first locking means (6) and the second locking means (7) engage with each other and prevent the dispenser (4) from being moved to the open position while the hot water is being supplied.
  • the first locking means (6) that starts cooling down moves away from the second locking means (7) and returns to the free position (A) and the dispenser (4) can be opened/closed after the hot water supply.
  • the dispenser (4) is enabled to be automatically locked in a mechanical manner while the hot water is being supplied and the safety of the washing machine (1) is improved in a simple and low cost manner.
  • the first locking means (6) is arranged on the dispenser (4) and the second locking means (7) is arranged on the housing (3).
  • the first locking means (6) is preferably positioned on an outer surface of the dispenser (4) so as not to be in direct contact with water.
  • the heat is transferred from the dispenser (4) to the first locking means (6), and the first locking means (6) moves from the free position (A) to the locked position (B) and bears against the second locking means (7) arranged on the housing (3).
  • the first locking means (6) is protected from corrosion and the cleaning agents are prevented from sticking on the first locking means (6) and hindering the operation of the first locking means (6).
  • the washing machine (1) comprises two first locking means (6) each on one side of the dispenser (4) and two second locking means (7) each on one side wall of the housing (3).
  • This embodiment is advantageous especially when the dispenser (4) has a plurality of compartments (10) wherein the detergent is loaded, and when only the left compartment (10) or only the second compartment (10) is supplied with hot water, the first locking means (6) that is close to the respective compartment (10) is enabled to move to the locked position (B).
  • the first locking means (6) has the form of a straight strip in the free position (A).
  • the first locking means (6) has the form of a flat plate and extends on the surface the same is attached to in a manner parallel to the surface.
  • the second locking means (7) is prevented from getting caught on the structures in the housing (3) and blocking the movement of the dispenser (4) while the dispenser (4) is moved between the open position and the closed position.
  • the first locking means (6) is fixed at one end such that the other end thereof bends towards the second locking means (7) in the locked position (B).
  • the first locking means (6) is fixed at one end so that the free end thereof changes position relative to the free position (A) while shifting to the locked position (B).
  • the first locking means (6) is fixed at the center thereof by means of a support (8).
  • the support (8) By means of the support (8), the bending motion of the first locking means (6) is limited and the free end of the first locking means (6) is prevented from bending uncontrollably and getting stuck between the housing (3) and the dispenser (4).
  • the first locking means (6) is prevented from moving away from the dispenser (4) excessively in the locked position (B) and almost half of the first locking means (6) is kept in the vicinity of the surface of the dispenser (4).
  • the effectiveness of the heat transfer between the first locking means (6) and the dispenser (4) is maintained while the former is in the locked position (B).
  • the second locking means (7) has the form of a recess that receives the first locking means (6) in the locked position (B).
  • the second locking means (7) has the form of a cavity formed on the housing (3) and wherein the first locking means (6) is fitted in the locked position (B).
