  • the heater is turned off with the signal delivered to the control unit from the heat sensor located in the tub in an area close to the heater. Decreasing the energy consumption of the washing machine is directly proportional with decreasing the energy consumption in the heating stage.
  • the amount of electric energy consumed in the heating stage depends on the amount of water heated for a water intake temperature of constant value. Depending on how much more this amount of water is, the heating duration and electric energy consumption in the heating stage will be that much more.
  • the wash water received at a level that will saturate the amount of laundry in the drum, is started to be heated after a 10 -15 min. of cold washing step.
  • the water to be received into the washing machine is determined based on the level and not on the amount. Therefore, when the washing machine is loaded at full capacity with the same type of laundry, the amount of received wash water is not always a constant value. Since water intake is determined by performing level measurement with the aid of the pressure sensor, the turbulences in the drum, water absorption characteristics of the laundry, the amount of detergent, water entry temperature and similar factors cause variations in the amount of water that saturates the laundry load. This situation directly results in variability of the heating duration and the energy consumption. As a result of the measurement errors that arise due to the configuration of
  • the amount of wash water becomes much more than the required value, therefore the energy consumption can increase considerably and results in nonconformity with the energy consumption declarations.

  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, is a machine wherein the amount of water received is determined by the level measurement and the control unit determines the estimated time period that will elapse for the temperature of the wash water to reach the value determined by the manufacturer. If this estimated time period is longer than the maximum time determined by the manufacturer, it is decided that the amount of wash water is more than the amount of water predetermined by the manufacturer for the selected program, thereby the temperature of the wash water is provided to be decreased. Thus, the same washing performance is provided to be achieved without a change in energy consumption by compensating the excess wash water with low temperature of the wash water.
  • the estimated time period is shorter than the maximum time determined by the manufacturer, it is decided that the amount of wash water is less than the amount of water for the selected program predetermined by the manufacturer, and the temperature of wash water is provided to be increased up to the temperature for each textile type that will not damage that type of textile product. Consequently, the same washing performance is provided to be achieved without a change in washing performance by compensating less wash water in response to high temperature wash water.

  • the amount of wash water received from mains is determined by performing level measurement.
  • the washing performance intended for the selected program is provided by washing with water received more than the desired amount. Furthermore, when less than the determined amount of water is received for the washing program, the intended washing performance is this time achieved by increasing the wash water temperature even though there is less wash water. Consequently, the variabilities in energy consumption and washing performance are minimized and thus, the most optimum values in between the energy consumption and washing performance are provided to be achieved.
  • the washing program starts when the user operates the washing machine (1 ) and selects the washing program depending on desired parameters such as the type of laundry, dirt level and the like.
  • water at a certain temperature is received from the mains into the washing machine (1 ) and the water received into the washing machine (1 ) starts to be heated by operating the heater (4) preferably after washing with cold water for a certain period of time. While the heater (4) is activated, the estimated time period (th) that will elapse for reaching the wash water target temperature value (T) predetermined by the manufacturer for each washing program is determined.

  • the wash water target temperature value (T) is decreased to a lower temperature value.
  • the washing performance intended for the selected washing program is provided to be achieved with more water by operating the heater (4) for a shorter period of time or with lower power. Consequently, the washing performance intended for the selected washing program is achieved by saving the energy to be consumed for heating the wash water received in excess of the amount determined for the selected washing program.
  • the wash water target temperature value (T) is increased to a higher temperature value.
  • the washing performance intended for the selected washing program is provided to be achieved with less water by operating the heater (4) for a longer period of time or with higher power. Consequently, the same washing performance intended for the selected washing program is achieved by increasing the temperature of the wash water in response to receiving wash water less than determined for the selected program.
  • the amount of temperature increase is a value for each textile type that will not damage that textile product.
  • the present invention when the amount of wash water received for the selected washing program is in excess, the same washing performance is provided to be achieved by decreasing the target temperature value (T), thereby decreasing the amount of energy that will be consumed for heating the excess water. Furthermore, in the situation when the amount of wash water received is insufficient for the selected washing program, the decrease in washing performance that will arise resulting from washing with less water is compensated by increasing the target temperature value (T), thereby providing the intended washing performance to be achieved.
