Description

A DISHWASHER COMPRISING A HEATER
The present invention relates to a dishwasher comprising a heater.
In dishwashers used today, a washing cycle is completed by successively performing the cold washing, main washing, rinsing and drying steps. Water is delivered onto the dishes placed on the racks by means of spray arms. The flow rate and density of the water delivered onto the dishes can be changed depending on the position and geometry of the holes on the spray arm, and the cleaning process is realized. Aft the completion of the washing steps, the water droplets remaining on the dishes are evaporated. Afterwards, the remaining water droplets are sucked from the dishes by means of a fan. Thus, the dishes are dried. Nowadays, the users expect from the dishwashers good washing and drying performances in a shorter time. Therefore, the use of quick washing programs becomes widespread. However, since the drying duration in the quick washing programs is short, the time required for evaporating the water droplets on the dishes cannot be provided. Moreover, discharging the hot water from the machine in the discharge step and the intake of cold water into the machine in the water intake steps cause significant heat losses. This causes waste of time and energy.
In the state of the art Utility Model No. CN206228312, a dishwasher is disclosed, comprising a fan and a heater disposed on the air duct, thus improving the drying performance.
