  • Prior art washing devices used for cleaning textile products may comprise a quick washing operation for cleaning the laundry in a fast manner in particular if there is a time limitation, as well as a normal washing operation for cleaning the laundry at normal washing time period.
  • this quick washing operation either the laundry cannot be cleaned as desired or it allows a very small amount of laundry to be cleaned as desired. In that case, quick washing process cannot be used and user needs cannot be met in cases where laundry amount is large and effective cleaning is required.
  • a heater enabling the water to be heated is located either at a tub of the washing device or a circulation line for circulating water between the tub and drum.
  • the circulation system cannot be activated while the water is heated and the water cannot be heated during a circulation process since a certain level of water is required for the heater to operate.
  • the temperature of water decreases extremely as a heating process cannot be performed, therefore it is not possible to wash a large amount of laundry with the quick washing operation.
  • the heater provided on the line is operated at a low power for avoiding lime depositing and preventing a thermal protector from becoming active.
  • a good washing performance is achieved with the normal washing operation and a large amount of laundry is able to be washed in an efficient manner; however, with the quick washing operation, an efficient cleaning cannot be achieved because heating of water takes a long period of time due to the low operating power.

  • the operation method comprises the steps of: selecting the quick washing operation by the user by means of a control panel provided at the washing device; then, initiating the water intake process and receiving water into the tub via the delivery line to provide accumulation of water in the tub, and at the same time, initiating rotation of the drum to proceed to the main washing process of the quick washing operation; after receiving a first amount of water stored at the control unit into the tub, operating a first heater located at the tub for a first time period stored at the control unit and stopping operation of the first heater at the end of the first time period; after the first time period is completed, operating the pump to initiate recirculation process of water between the tub and the drum, and performing the recirculation process and operating a second heater located at the circulation line for a second time period stored at the control unit; stopping operation of the pump and the second heater at the end of the second time period, and then, operating the first heater for a third time period stored at the control unit; operating alternately the first heater and the second heater at said second and third time periods for a fourth
  • An object of the present invention is to provide a washing device having a quick washing operation, and an operation method thereof.
  • Another object of the present invention is to provide a washing device which provides an efficient washing with the quick washing operation, and an operation method thereof.
  • Yet another object of the present invention is to provide a washing device performing the quick washing operation without compromising the amount of laundry to be washed, and an operation method thereof.
  • a further object of the present invention is to provide a washing device in which temperature of water is enabled to reach a required temperature in a short span of time, and an operation method thereof.
  • FIG. 1 is a schematic view of an exemplary embodiment of the washing device according to the invention.
  • Washing devices used for cleaning textile products generally comprise at least one tub; at least one drum which is located in the tub so as to be rotatable around an axis; at least one circulation line enabling the water received into the tub to be recirculated and returned to the drum; and a pump for performing the circulation.
  • a heater is used for heating the water, wherein the heater may be located at the tub or the circulation line.
  • use of the heater either causes undesired washing performance due to the water not being able to reach a sufficient heat in a short span of time with the quick washing operation, or allows a lower amount of laundry to be washed than the laundry amount of the normal washing operation. This affects user satisfaction in a negative manner.
  • a washing device for solving said problems, and an operation method thereof.
  • the washing device has at least one normal washing operation and at least one quick washing operation which provides washing in a shorter time than the normal washing operation (the quick washing operation has at least one water intake process, at least one main washing process, at least one rinsing process and at least one spinning process), wherein the washing device further comprises at least one tub (1) having at least one outlet (5); at least one drum (2) which is located in the tub (1) so as to be rotatable around an axis; at least one delivery line (3) for transferring water from a water source (e.g.
