Abstract
A dishwasher includes a chamber containing the dishes, a heater for heating the air in the chamber, a water inlet provided on the upper side of the chamber, a drain pump for draining the water from the chamber, an air circulation passage through which the air in the chamber is circulated, a fan for circulating the air in the chamber through the air circulation passage, a dehumidifying surface capable of holding water provided in the air circulation passage, and a microcomputer for controlling the drain pump, the fan and the volume of the water supplied from the water inlet. In a drying cycle, the air heated by the heater is circulated through the air circulation passage. Since the air contacts with the water spread over the dehumidifying surface, and is cooled down, the water is condensed from the air. Therefore, when the air is heated again, the evaporation of the drops of water on the dishes increases.
