  A plurality of inwardly facing projections 39 are provided on the upper surface of the housing 17, and a recess 38 is provided below the projections 39 and above the inner lid 27. In addition, a plurality of vent holes 41 are provided at a position lower than the exhaust port 33 at the rear portion of the housing 17, and the exhaust from the exhaust port 33 is discharged to the outside of the housing 17.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the operation is started, cleaning water is supplied into the cleaning tank 20, and the cleaning water is heated by the heater 40 disposed at the bottom of the cleaning tank 20. At the same time, cleaning water is sprayed from the cleaning nozzle 24 toward the tableware 19 by the cleaning pump 25, and a cleaning process is performed to clean the tableware 19. Thereafter, the rinse water is replaced by a predetermined number of times, and then the rinse process is performed while the rinse water is heated to about 80 ° C. by the heater 40. Thereafter, the air in the cleaning tank 20 is heated by the heater 40 while the outside air is blown into the cleaning tank 20 by the blowing means 32. At the same time, the air containing a large amount of water is discharged from the exhaust port 33, and a drying process for drying the tableware 19 and the inside of the washing tub 20 is performed to finish the operation.

The adjusting means 36 is in a state in which the path from the first blower path 34 to the cleaning tank 20 is fully closed before the operation is started. The operation is started, and in the cleaning process, the adjusting means 36 keeps the path from the first blower path 34 into the cleaning tank 20 fully closed, and the temperature of the cleaning water reaches a constant temperature (for example, 40 ° C.). The operation of the air blowing means 32 is started, and the air blowing means 32 blows air only to the second air blowing path 37. At this time, only the outside air through the second air passage 37 is blown to the exhaust passage 35, so that the outside air is mixed with air or steam containing a lot of moisture leaked to the exhaust passage 35 due to thermal expansion in the cleaning tank 20. To do. Thereby, while reducing the temperature of the exhaust from the exhaust port 33 and reducing the amount of moisture per exhaust volume, dew condensation in the housing 17 is suppressed even if exhausted into the housing 17. be able to.

  Further, since the exhaust port 33 is arranged so that it can be viewed through the gap between the casing 17 and the inner lid 27, the exhaust contacts the upper surface of the casing 17 at a temperature equivalent to the outside air temperature and further reduces the temperature. As a result, the air can be discharged from the vent 41 to the outside of the apparatus, and even if condensation is formed on the upper surface of the housing 17, it can be recovered by the inner lid 27 below.

  In the rinsing process, since the temperature in the cleaning tank 20 continues to be high from the cleaning process, the blowing means 32 is operated while the path from the first blowing path 34 to the cleaning tank 20 is fully closed, and the inside of the casing 17 It is possible to exert the same effect that suppresses the dew condensation at.

  Next, in the drying process, the adjusting unit 36 is controlled so that the air blown from the air blowing unit 32 is initially branched from the first air blowing route 34 to the second air blowing route. In this way, a larger amount of outside air is blown from the second blower path 37 than the air that is blown (exhausted) from the first blower path 34 through the cleaning tank 20 and contains a lot of moisture. To do. As a result, the exhaust temperature from the exhaust port 33 and the amount of water per exhaust capacity can be reduced and exhausted, and condensation in the housing 17 can be suppressed.

  Thereafter, as the temperature in the cleaning tank 20 detected by the temperature detecting means 23 decreases, the amount of air blown through the cleaning tank 20 is adjusted to increase. Thereby, drying can be accelerated | stimulated and shortening of drying time can be aimed at.

  Further, by providing the projection 39 on the upper surface of the housing 17 inward, the contact area with the exhaust is increased, and the temperature of the exhaust is further lowered due to the temperature difference with the upper surface of the housing 17 close to the outside air temperature. Can do. Furthermore, when the humidity of the exhaust at the initial stage of the exhaust process is high and the temperature difference from the upper surface of the housing 17 is large, the moisture of the exhaust can be collected as condensed water.

  Further, since the concave portion 38 is provided on the upper surface of the inner lid 27 so that water can be stored, the condensed water collected on the upper surface of the housing 17 and collected by the protrusion 39 is easily recovered. The recovered condensed water can be dried during operation by the residual heat of the inner lid 27 that becomes high during the drying process and the exhaust gas whose humidity gradually decreases.

  Further, since the vent 41 is provided at a position lower than the exhaust port 33, the exhaust passing between the casing 17 and the inner lid 27 from the exhaust port 33 collides with the rear portion of the casing 17, and the vent 41 It is discharged outside. At this time, a slight condensation can be caused by heat exchange with the rear portion of the casing 17, and the air can be exhausted outside the apparatus with a lower humidity. Condensation is dried by exhaust gas with gradually decreasing humidity, but if dew condensation water remains due to conditions such as low outside air temperature, it can be quickly recovered by residual heat in the cleaning tank 20 by collecting it at the bottom of the housing 17. It can be dried and processed easily.

  As a result, even when the user is in use or not in use, the user can use the product without worrying about working in front of the dishwasher or exhausting when passing, Condensed water can be quickly evaporated and easily treated while suppressing condensation.

  As described above, the dishwasher according to the present invention should be used without worrying about exhaust when working in front of the dishwasher or passing through by not exhausting air from the front of the dishwasher. Therefore, it is useful as a dishwasher of the type used by being built into the system kitchen.
