Therefore, even if the user is in front of the dishwasher main body, steam is not directly applied. This steam has a temperature of about 60 ° C., and is not so vigorous or intense that it is not at the level of burns, and the steam is not surprised at places unexpected by the user. Furthermore, even if there is a hanging cabinet or the like above the dishwasher main body, it is difficult for steam to hit directly, and corrosion around the kitchen due to condensation can be prevented. In addition, it is possible to improve drainage during washing and drying, and to reduce residual water droplets.

(Embodiment 2) As shown in FIGS. 1 and 2, the top surface 42 of the inner lid 26 is
The bowl has an upwardly convex bowl shape so that large platters can be stored. The blower guide plate 33 is attached to the inner surface of the inner lid 26 along its bowl shape, and the bottom surface 43 of the blower guide plate 33 is inclined rearward and downward with a certain interval from the top surface 42. Other configurations are the same as those of the first embodiment.

The operation of the above configuration will be described.
During the washing, the washing water enters the inside of the air guide plate 33 through the discharge hole 35, but since the inner surface of the inner lid 26 is bowl-shaped, the bottom surface 43 of the air guide plate 33 is greatly inclined downward. Therefore, the washing water does not easily flow down from the discharge hole 35 into the washing tank 21 and the washing water does not accumulate in the air guide plate 33.

Further, even during drying, the air guide plate 33
Dew forms due to steam passing through the inside, but easily flows down the discharge hole 35 into the cleaning tank 21 along the bottom surface 43, and the inside of the air guide plate 33 can be dried quickly.
Since the steam discharged from 1 goes out higher and obliquely forward than the rear of the upper surface of the inner lid 26, the steam can be prevented from being poured even when the user is in front of the dishwasher.

Therefore, the drying performance can be improved without the dew condensation water dripping onto the crockery 22 which is about to dry during the drying, and the crockery 22 is not wetted. Here, the inclination of the bottom surface 43 for improving drainage can be formed along the bowl shape of the inner lid 26, so that the configuration can be made without sacrificing the effective volume of the cleaning tank 21.

(Embodiment 3) As shown in FIGS. 1 and 2, the exhaust port 31 is
The exhaust port 31 is formed integrally with the top surface of the outer lid 2.
7 protrudes to the surface side from the hole 32, and constitutes a part of the appearance of the dishwasher main body. A ventilation guide plate 33 is attached to the inside of the tank of the inner lid 26 so as to cover the exhaust port 31, and a discharge hole 35 is formed in a lower end portion 34 of the ventilation guide plate 33.
Is formed.

The operation of the above configuration will be described. During the cleaning, the cleaning water enters the inside of the air guide plate 33 through the discharge hole 35. However, since the discharge hole 35 is located at a position away from the exhaust port 31, the cleaning water is discharged. The air does not fly out of the air outlet 31. Here, since the air guide plate 33 is located inside the tank, it is not necessary to seal the space between the inner lid 26 and the air guide plate 33 with a seal member or the like. Therefore, with this configuration, it is possible to obtain a highly reliable airflow path free from the risk of water leakage without increasing the cost with a small number of parts.
