Drying system for a dishwasher

Abstract

The present invention describes a drying system for a dishwasher having a washing tub (2). The drying system comprises: a first fan (3) for propelling a first air stream through the washing tub (2) toan air transporting space (9) situated in the dishwasher outside the washing tub (2), wherein the first air stream is propelled in such a way that humidity in the washing tub (2) is absorbed by the first air stream and propelled to the air transporting space (9); and a second fan (4) for propelling a second air stream received from an area outside the dishwasher to the air transporting space (9).The drying system is further arranged such that the first and the second air streams are mixed in the air transporting space (9), and in that the mixed air stream is propelled to an exhaust opening (10) leading out from the dishwasher. Thereby, an efficient drying process can be achieved wherein air leaving the dishwasher has an appropriate temperature and humidity.

Description

technical field [0001] The invention relates to a drying system for a dishwasher. This drying system can be effectively used in drawer dishwashers. Background technique [0002] After the items have been washed in the washing process of the dishwasher, the items are dried in a drying process. To carry out such a drying process, the dishwasher is equipped with a drying system. [0003] GB 2263969 shows a closed drying system in which a first fan circulates the air in the closed system through circulation ducts into and out of the washing chamber. In addition, a second fan pushes air received from outside the dishwasher through another duct in the dishwasher, and pushes it further to the exhaust outlet, back out of the dishwasher. A heat exchanger is located between the two pipes. Therefore, the hot and humid air from the washing chamber is cooled by the cold air received from the outside, and the humid circulating air is condensed into water, and the less humid air is ret...

AI Technical Summary

Problems solved by technology

Such a solution is more efficient than a fully closed system and the exhaust air is cooler, however, the efficiency is not as high as in an open system

Another disadvantage of this solution is that, after the dishwasher has already been installed, the exhaust section does not take into account whether the drying process has just started, or is in its final stage, nor the possible different drying programs that the dishwasher can select, This causes the exhaust air to be variable in temperature and humidity
