I am placing it. Below the dish basket 19, the washing nozzle 20 which sprays washing water is rotatably provided, and the pump 21 which circulates the washing water collected in the washing tank 16 via the washing nozzle 20 is carried out. I am preparing. Moreover, the heater 23 which heats the washing water and the air blown by the 1st blower 22 is arrange | positioned at the bottom part of the washing tank 16. As shown in FIG.

The exhaust port 24 is disposed between the front panel 25 and the cleaning tank 16 provided in front of the cleaning tank 16, and the air in the cleaning tank 16 is exhausted by the first blower 22. The exhaust gas is discharged by 24) and disposed above the cleaning tank 16. In addition, an opening 26 communicating with the outside air is provided above the front panel 25, and the exhaust port 24 and the opening 26 are communicated by the exhaust path 27.

The second blower 28 has the same blowing capability as that of the first blower 22, and blows the air through the opening 26 through a blower path 29 in which the outside air is disposed behind the front panel 25. It is composed. The blowing path 29 is disposed so as to be in surface contact with the exhaust path 27 in the front-rear direction, and the air discharged from the cleaning tank 16 through the exhaust port 24 and the exhaust path 27 through the opening 26. And the outside air sent by passing the blowing path 29 from the second blowing section 28 to mix.

In addition, the lower part of the washing tank 16 is provided with a temperature detecting unit 30 for detecting the temperature of the washing water, and the control unit 31 for gradually controlling the washing, rinsing and drying processes is applied to a signal from the temperature detecting unit 30. The driving time of the first blower 22 and the second blower 28 is controlled. In the drying step, the first blower 22 is operated while the air in the cleaning tank 16 is heated by the heater 23, and the second blower 28 is simultaneously driven.

At this time, the control part 31 controls so that the 1st air blower 22 may be intermittently operated so that the air volume of the 1st air blower 22 may become smaller than the air volume of the 2nd air blower 28.

Moreover, the 1st rail 32 is being fixed to the side surface of the washing tank 16, and the 1st rail 32 is moved in parallel in the front-back direction by the 2nd rail 33 fixed to the dishwasher main body 15.

In addition, although it is good to operate the 2nd air blower 28 continuously, intermittent operation can also control the amount of air | fever required as needed in order to diffuse the moisture of exhaust, and it is continuous operation in the beginning of a drying process especially when it contains a lot of moisture. The air volume may be gradually reduced. In this case as well, each operation time may be controlled so as to reduce the air volume of the first blower 22 rather than the air volume of the second blower 28.

Thus, according to this embodiment, the cleaning tank 16 provided in the dishwasher main body 15, the cleaning nozzle 20 provided in the washing tank 16, and the air in the cleaning tank 16 exhaust path 27 A first blower 22 for discharging to the outside through the air, and a second blower 28 for mixing outside air through the blower path 29 to air discharged from the exhaust port 24 through the exhaust path 27; The control part 31 is provided with the control part 31 which controls each process of washing | cleaning, rinsing, and drying gradually, and the control part 31 drives the 1st air blower 22 also during operation of the 2nd air blower 28 in a drying stroke. To control. As a result, the outside air having a low temperature and low temperature supplied to the opening 26 by the second air blowing unit 28 through the air blowing path 29 is mixed with the heated steam discharged from the exhaust port 24 to open the opening. The exhaust temperature of the exhaust wind discharged from (26) is lowered, and moisture contained in the exhaust wind is diffused. Therefore, condensation is prevented from occurring in the countertop 40a of the system kitchen 40 in which the front panel 25 and the dishwasher main body 15 are accommodated, and at the same time, the steam discharged from the exhaust port 24 allows the air flow path ( It is possible to prevent the flow into the second blower 28 through 29) or leak out to the outside.

Moreover, the control part 31 reduces the air blow ability of the 1st blower 22 by controlling so that the operating time of the 1st blower 22 may be shorter than the operation time of the 2nd blower 28, With respect to the air volume flowed into the exhaust path 27 by the outside air by the second blower 28, the air volume by the first blower 22 is suppressed, and the humid air in the cleaning tank 16 is exhausted. It is possible to prevent the leakage to the opening 26 via).

Moreover, the control part 31 can adjust the air volume by the 1st air blower 22 easily by intermittent operation control of the 1st air blower 22. FIG.
