Therefore, excessive negative pressure in the internal space S of the apparatus main body 10 due to the exhaust action of the exhaust port 42 is suppressed. Therefore, in the cooking chamber 100, the air around the dishwasher 1 can be prevented from being excessively sucked into the inlet opening 11 and the outlet opening. As a result, an increase in the air conditioning load due to the introduction of outside air can be prevented, and when the air conditioning capacity is exceeded, the temperature and humidity of the room become inappropriate and the working environment of the cooking chamber 100 may deteriorate. Can be prevented. Moreover, since it is prevented that the water vapor | steam and hot air with which the washing room | chamber interior of the dishwasher 1 is filled up are excessively absorbed, it is suppressed that the heat of washing water is discharged | emitted excessively and it prevents that thermal efficiency falls. can do.

In addition, the washing chambers S ₁ , S ₂ , and S ₃ are filled with steam or air (hot air) by washing water that is hot water or hot water used for washing dishes. There is a concern that steam or air (hot air) in the cleaning chamber is exhausted and thermal efficiency is lowered. However, in the present embodiment, since the air supply port 40 having an action of introducing external air is provided inside the exhaust port 42 (the side far from the inlet opening and the outlet opening), steam and air (hot air) Emission can be suppressed. Therefore, waste of energy can be suppressed by maintaining the atmospheric temperature in the cleaning chamber and thus the heat of the cleaning water. Even when the inlet opening and the outlet opening become one (common), the exhaust port 42 may be provided near the opening, and the air supply port 40 may be provided at a position farther from the opening than the exhaust port 42.

In the present embodiment, since the rectifying plate 15 is provided in the vicinity of the air supply port 40 and the exhaust port 42, the supply of air into the apparatus main body 10 and the discharge of air from the apparatus main body 10 are efficient. Done.

Thus, for example, the air from the upstream side air supply port 40a is supplied to the apparatus body 10 while preventing be discharged directly from the adjacent upstream outlet 42a, from the washing chamber S ₃ of the excess steam is discharged Therefore, steam and air near the inlet opening 11 can be efficiently discharged.

  Further, in the present embodiment, since the wind direction plate 16 is provided in the vicinity of the air supply port 40 and the exhaust port 42, the supply of air into the apparatus body 10 and the discharge of air from the apparatus body 10 are efficient. Done. That is, the first upstream wind direction plate 16a is provided on the upstream side of the upstream exhaust port 42a, that is, on the side close to the inlet opening 11, and particularly protrudes in the downstream direction from the ceiling surface of the apparatus main body 10. Is provided. A second upstream wind direction plate 16b is provided in the vicinity of the downstream side of the upstream air supply port 40a. Further, a second upstream wind direction plate 16b is provided so as to protrude from the ceiling surface of the apparatus body 10 toward the upstream direction. Therefore, air discharged from the apparatus main body 10 through the inlet opening 11 to the outside can be suppressed.

The first downstream louver 16c is provided so as to protrude toward the downstream direction from the ceiling surface is the downstream side near the rinse chamber S ₃ of the apparatus body 10. Therefore, it is possible to air supplied from the downstream side air supply port 40b is suppressed from flowing into the rinsing chamber S ₃ side. A second downstream wind direction plate 16d is provided in the vicinity of the downstream side of the downstream exhaust port 42b. Further, a second downstream wind direction plate 16d is provided so as to protrude from the ceiling surface of the apparatus body 10 toward the upstream direction. Therefore, air exhausted from the apparatus main body 10 through the outlet opening 13 can be suppressed.

  In the present embodiment, the air supply pipe damper 50 and the air discharge pipe damper 52 act to supply air (volume of air supplied per unit time) and discharge (discharged per unit time). The volume of air, hot air, and water vapor) can be easily adjusted. Therefore, according to the situation of the space (cooking room 100) in which the dishwasher 1 is arranged, it is possible to set the optimal air supply amount and discharge amount to the dishwasher 1. In the present embodiment, so-called dampers such as the air supply pipe damper 50 and the air discharge pipe damper 52 are used as the air amount adjusting means for adjusting the air supply amount and the discharge amount. However, instead of these dampers, other types of air amount adjusting means such as valves (air supply valve and exhaust port valve) and fan speed control can be used. There is no particular limitation as long as the device can be adjusted.

  In general, it is preferable that the amount of air supplied from the air supply port 40 is set to be smaller than the amount of air discharged from the exhaust port. Thereby, steam and air (hot air) can be prevented from being discharged to the outside from the inlet opening 11 and outlet opening 13 of the apparatus main body 10, and the working environment can be prevented from deteriorating due to steam and air (hot air).
