Description
- The present invention relates to a dishwasher which provides efficient drying.
- In dishwashers, the washing process is composed of certain steps. By means of the prewashing step, the dirt on the dishes is removed. After the prewashing step, the temperature of the water is increased, and the main washing step is performed wherein the cleaning is realized with hot water and detergent. In the main washing step, the oil residues and dirt on the dishes are removed. In the rinsing steps after the main washing step, the detergent residues and dirt residues are removed from the surfaces of the dishes. After the rinsing step, the drying step is performed. By means of the drying step, the water droplets on the dishes are dried. Thus, the formation of stains on the dishes is prevented and the dishes are unloaded from the machine in a dry state. In order to ensure an efficient drying step, the dishes are heated before the drying step. The heating process is realized by heating the water. The sooner the steam on the heated dishes is removed from the washing tub, the more efficient the drying process becomes. It is known that the rapid removal of the hot air in the washing tub from the tub during the drying process increases the drying performance. However, since the temperature inside the washing tub is very high, it is not possible for the user to open the door until the temperature drops.
