In addition, the foreign matter generated in the cleaning process is caught by a filter (not shown) provided in the sump 190, it is crushed finely by a disposer mounted in the sump 190. When the washing process is completed, the contaminated washing water is discharged to the outside of the dishwasher 100 through a drain pump (not shown) together with the foreign matter.

In addition, when the washing water is discharged to the outside, clean washing water is introduced into the sump 190 again through the washing water inlet, and sprayed through the spray nozzles 150 and 160 in the same manner as the washing step. Then, the rinsing step is performed using the clean washing water sprayed.

In addition, when the rinsing step is completed, by going through the drying step, the washing action is completed. Here, in the drying step, the hot air is introduced into the tub 110 to absorb moisture contained in the dish. Therefore, the air in the tub 110 is converted from the high temperature dry state to the high temperature and high humidity state. The hot and humid air is discharged to the outside of the tub through the air duct 50 stacked on the air brake 10 outside the tub, and condensation is performed. Here, the process of discharging the wet steam through the air duct 50 will be described later with reference to the drawings.

On the other hand, with reference to the accompanying drawings will be described in detail the function of the air brake.

Then, the water supplied is dropped to the center portion of the air brake 10 is collected in the water softener connector (15). Then, the water softener is connected to a sump (not shown) through an ion exchange resin filter formed in the softener through the water softener connector 15. Then, when the washing water is continuously supplied, the water rises inside the air brake 10, and a part of the filled water is collected into the regenerator connector 16 formed next to the softener connector 15.

In addition, an air inlet 20 is formed at an upper edge of the air brake 10 to allow air to enter from the outside. The suctioned air communicates with the siphon prevention gap 13 formed on the upper flow path of the air brake 10, thereby preventing the siphon phenomenon in which water continuously flows while the water supply is stopped.

On the other hand, the washing water collected in the softening device connector 15 is softened to facilitate the washing operation by filtering impurities contained in the raw water while passing through the ion exchange resin filter provided in the softening device.

In addition, the washed dirty water flows along the drain passage through the sump drain connector 17, and is discharged to the outside of the dishwasher along the drain hose (not shown) connected to the drain hose connector (18). A small amount of washing water collected in the regenerator connector 16 passes through the regenerator to purify the ion exchange resin filter. Here, the air brake 10 is partitioned into a condensation chamber 50 and a regeneration water chamber 21 by partition walls.

In addition, the condensation chamber unit 50 is formed with an inlet pipe 51 through which high temperature steam is introduced, and an outlet pipe through which condensed water flows out between the water softener connector 15 and the regenerator connector 16. 52 is formed. Therefore, the humid air passing through the inlet pipe 51 is naturally heat exchanged while passing through the side surface of the regeneration water introduced into the air brake 10, thereby condensing into water and flowing back into the sump through the outlet pipe 52.

A guide tube 54, an inlet tube 51 through which the wet air introduced through the guide tube is introduced, and an outlet tube 52 through which the wet air introduced through the inlet tube is condensed and discharged.

In detail, a part of the washing water is supplied through the tub connector 14 of the air brake 10 while the washing is in progress. Here, cold tap water is filled in the regeneration water chamber 21 of the air brake 10. The regeneration water chamber 21 is partitioned from the condensation chamber 50 by a partition wall. In other words, the condensation chamber 50 may be stacked in two layers by a partition to correspond to the shape of the air brake 10 on the front or rear surface of the air brake 10. Therefore, the cold tap water fills the regeneration water chamber 21 to a predetermined height, and hot steam flows into the condensation chamber 50.

Meanwhile, a steam discharge groove 111 is formed at a predetermined portion of the tub 110. Then, the blower 55 according to the present invention is mounted in the vapor discharge groove. Therefore, the hot and humid air in the tub is sucked through the blower 55 during the drying process. In addition, the hot and humid air introduced through the blower 55 is guided to the inlet pipe 51 through the guide tube 54 and introduced into the condensation chamber 50, thereby easily condensing.

In addition, although the guide tube 54 is shown in the drawings presented in the present invention, the guide tube 54 is not configured, and the blower 55 and the inlet tube 51 may be directly connected. Of course.

Here, the wet air introduced into the condensation chamber unit 50 is naturally heat exchanged through the partition wall due to the temperature difference between the cold tap water filled in the regeneration water chamber unit 21 described above, and the wet air is condensed with water to form a lower portion of the condensation chamber unit. It flows down the outflow pipe 52 formed in the.

In addition, the lower end portion of the condensation chamber 50 is gradually narrower in the downward direction, has a shape that is collected in the outlet pipe (52). Therefore, the water condensed in the condensation chamber 50 is easily concentrated in the outlet pipe. The water flowing into the outlet pipe 52 is directly guided to the sump and reused again. In addition, although the lower end portion of the condensation chamber part 50 may be molded to have a narrow width, alternatively, the inclined rib may be formed in the condensation chamber part to condense the water condensed in the outlet pipe.
