  • This specification also provides a method for controlling a washing machine, including: supplying water to a detergent box to provide detergent introduced in the detergent box to the laundry; controlling water supply to the detergent box according to whether or not the detergent box is opened or closed as detected by the detergent box opening/closing detecting member; and stopping water supply to the detergent box if the detergent box is detected to be open in the step of controlling water supply to the detergent box.
  • the detergent box opening and closing detecting apparatus of a washing machine and a method for controlling a washing machine having the same have the following advantages.
  • the detergent box If the detergent box is opened in the water supply process, the water supply can be stopped. Thus, a softening agent or a bleaching agent cannot be improperly supplied at an early stage, and thus, the detergent introduced in the interior of the detergent box cannot splash to the outside to contaminate the surroundings.
  • FIG. 1 is a perspective view of a washing machine employing a detergent box opening/closing detecting apparatus according to an exemplary embodiment of the present invention
  • FIG. 2 is a plan view of the detergent box opening/closing detecting apparatus of the washing machine according to an exemplary embodiment of the present invention
  • FIG. 3 is a schematic block diagram showing the configuration of the detergent box opening/closing detecting apparatus of the washing machine according to an exemplary embodiment of the present invention.
  • FIG. 4 is a flow chart illustrating the processes of a method for controlling the washing machine including the detergent box opening/closing detecting apparatus according to an exemplary embodiment of the present invention.
  • a detergent box opening/closing detecting apparatus of a washing machine and a method for controlling a washing machine including the same will now be described with reference to the accompanying drawings.
  • the detergent box opening/closing detecting apparatus of a washing machine and a method for controlling a washing machine including the same are applied to a drum type washing machine, but it is merely an example and the detergent box opening/closing detecting apparatus of a washing machine and a method for controlling a washing machine including the same can be also applicable to an automatic washing machine.
  • FIG. 1 is a perspective view of a washing machine employing a detergent box opening/closing detecting apparatus according to an exemplary embodiment of the present invention.
  • a drum (not shown) is rotatably inserted in a main body 101 of a washing machine according to an exemplary embodiment of the present invention.
  • a front panel 102 and a top cover 104 are installed on front and upper surfaces of the main body 101 .
  • a control panel 103 is installed between the front panel 102 and the top cover 104 and includes various manipulation keys, a display unit, etc.
  • Reference numeral 106 is a door which is rotatably hinge-combined to the main body 101 and opens and closes the drum.
  • a detergent box installation part 107 is formed at one side of the control panel 103 of the main body 101 of the washing machine.
  • a detergent box 110 is insertedly positioned in the detergent box installation part 107 such that it can be movable in an inward/outward direction.
  • washing may be performed on the laundry received in the drum as a motor (not shown) installed in the washing machine is rotated.
  • FIG. 2 is a plan view of the detergent box opening/closing detecting apparatus of the washing machine according to an exemplary embodiment of the present invention.
  • the detergent box 110 is positioned in the detergent box installation part 107 of the main body 110 of the washing machine.
  • the detergent box 110 as shown in FIG. 2 is partially inserted in the detergent box installation part 107 .
  • a lead switch 120 is installed in the detergent box installation part 107
  • a permanent magnet 130 is installed in the detergent box 110 , the lead switch 120 and the permanent magnet 130 are installed at positions such that they face each other.
  • the lead switch detects the closing of the detergent box 110 , and when the permanent magnet 130 becomes away from the lead switch 120 as the detergent box 110 is opened, the lead switch 120 detects the opening of the detergent box 110 .
  • the lead switch 120 and the permanent magnet 130 detect the opening and closing of the detergent box 110 installed at the detergent box installation part 107 , they can be defined as a detergent box opening/closing detecting member.
