Description

  • The present invention relates to a dishwasher which provides optimization.
  • In dishwashers, the cleaning process is carried out by delivering hot water and detergent onto the kitchen items. The water heated by the heater is delivered onto the dishes placed onto the rack. The detergent and the hot water provide the removal of the dirt particles from the dishes. Depending on the dirt level of the dishes, the user may choose different washing programs. As the degree of dirt increases, the amount of hot water used, and the temperature of the water and the washing time increase. Thus, it is aimed to take the kitchen items completely clean out of the dishwasher. The cleaning process varies according to the degree of dirt on the dishes. Water at lower temperatures is used for dishes with low dirt level, and shorter programs are preferred. Thus, savings in both water and energy are provided. However, the user may not always correctly determine the dirt level. When the washing process carried out is not suitable for the dirt level, the cleaning cannot be properly performed or water and energy consumption increases. In the state of the art, there are dishwashers which determine the washing program according to the dirt level. However, a program suitable for every dirt level cannot be selected and the cleaning process cannot be realized due to failure to correctly detect the dirt level. In case the user is not satisfied with the cleaning process, he/she may need to perform an additional washing process.
  • In the state of the art United States of America Patent No. US10194781 , a dishwasher is disclosed, which improves the step determined by the user.
  • The aim of the present invention is the realization of a dishwasher with improved washing efficiency.
  • The dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a washing tub which is disposed in the body; a door which is provided on the body; at least one rack which is disposed in the washing tub; at least one spraying member which sprays water onto the rack; a dirt measurement member which is disposed in the washing tub; and a control unit which controls the washing programs. By means of the water delivered onto the kitchen items through the spraying members, the cleaning process is performed. The dirt level of the dishes is measured by means of the dirt measurement member while the washing programs are controlled by the control unit.
  • The dishwasher of the present invention comprises a control unit which enables the washing program to be optimized with the user feedback depending on the data received from the dirt measurement member. The parameters of the washing program corresponding to the dirt level are predefined on the control unit. Standard programs are used as per user preference or the user can change the program parameters.
  • In an embodiment of the present invention, the dishwasher comprises the control unit which optimizes the program values depending on the feedback received from the user at the end of the washing program. After the dirt level is determined, the washing program is optimized depending on the user feedback. Thus, the next washing process for the same dirt level is performed with the optimized values.
  • In an embodiment of the present invention, the dishwasher comprises a control button which enables the user to control the optimization of the program values. When the control button is actuated by the user, the washing parameters are optimized.
  • In an embodiment of the present invention, the dishwasher comprises the control unit which provides the selection of the washing program suitable for the dirt amount determined by means of the dirt measurement member at the start of the washing program. Thus, the program which best corresponds to the dirt level and which is defined on the dishwasher is used.
  • In an embodiment of the present invention, the dishwasher comprises the control unit which controls the prerecorded energy and water consumption levels while determining the washing program suitable for the dirt amount. While the washing programs are optimized by means of the control unit, the energy and water consumption is also evaluated.
  • In an embodiment of the present invention, the dishwasher comprises a dirt measurement member which is a dirt sensor. The dirt sensor measures the dirt level.
  • In an embodiment of the present invention, the dishwasher comprises a dirt measurement member which is a turbidity sensor. The dirt level is determined by measuring the turbidity of the washing water.
  • In an embodiment of the present invention, the dishwasher comprises a dirt measurement member which is a conductivity sensor. The dirt level is measured depending on the conductivity level of the washing water.
  • By means of the present invention, a dishwasher is realized, comprising a control unit which enables the washing program to be determined depending on the dirt level and optimizes the washing program under the control of the user.
  • A dishwasher realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
    • Figure 1 - is the perspective view of the dishwasher.
