FIG.

The upper surface of the housing 17 is provided with a plurality of protrusions 39 in the inward direction. The recessed part 38 is provided in the upper part of the inner side cover 27 below the protrusion part 39. As shown in FIG. In addition, a plurality of vents 41 are provided in the rear portion of the housing 17 at a position lower than the exhaust port 33. The exhaust from the exhaust port 33 is configured to be discharged to the outside of the housing 17 through the vent 41.

The operation and action of the dishwasher configured as described above will be described below. When the operation of the dishwasher starts, the washing water is supplied into the washing tank 20, and the washing water is heated by the heater 40 disposed at the bottom of the washing tank 20. At the same time, the washing water is sprayed from the washing nozzle 24 toward the dishes 19 by the washing pump 25, and a washing step of washing the contaminants of the dishes 19 is performed. Thereafter, after the rinsing step is performed by replacing the predetermined number of washing water, the heating rinsing step is performed. In the heat rinsing step, the tableware 19 is rinsed while the washing water is heated to about 80 ° C. by the heater 40. Then, the air in the washing tank 20 is heated by the heater 40 while blowing outside air in the washing tank 20 by the blowing unit 32. At the same time, air containing a large amount of water is discharged from the exhaust port 33, and a drying process of drying the dishes 19 and the inside of the washing tank 20 is executed, and the dish washing machine ends the operation.

The adjustment part 36 is in the state which closed the path | route inside the washing tank 20 from the 1st ventilation path | route 34 completely before the operation | movement of a dishwasher. The operation of the dishwasher is started, and in the washing step, the adjusting unit 36 is a temperature at which the temperature of the washing water is constant while the path of the washing machine 20 is completely closed from the first blowing path 34. When the temperature reaches 40 ° C., for example, the operation of the blower 32 is started, and the blower 32 blows only the second blower path 37. At this time, only the outside air that has passed through the second blowing path 37 is blown into the exhaust path 35. As a result, outside air is mixed with air or steam containing a large amount of moisture leaked into the exhaust path 35 due to thermal expansion in the cleaning tank 20. As a result, the exhaust temperature from the exhaust port 33 decreases, and the amount of water per exhaust volume decreases. As a result, even if exhausted from the exhaust port 33 into the housing 17, condensation into the housing 17 can be suppressed.

In addition, since the exhaust port 33 is disposed so as to be visible from the gap between the housing 17 and the inner lid 27, the exhaust gas contacts the upper surface of the housing 17 at a temperature equivalent to the outside air temperature to further lower the temperature, thereby providing a vent. It is discharged out of the washing machine from 41. Moreover, even if it condenses on the upper surface of the housing 17, condensation water can be collect | recovered from the inner side cover 27 below.

In the rinsing step, since the temperature in the washing tank 20 continues from the washing step, the blower 32 is operated while the path from the first blowing path 34 into the washing tank 20 is in a fully closed state. The same effect of suppressing condensation in the housing 17 can be exhibited.

Next, in a drying process, the adjustment part is made so that the blowing air from the blowing part 32 may branch more to a 2nd blowing path rather than branching into the washing tank 20 via the 1st blowing path 34 initially. Controlled by 36. In this way, in the exhaust discharged from the exhaust port 33, the second blowing path 37 is higher than the air containing a large amount of moisture and having high temperature (vented) from the first blowing path 34 via the cleaning tank 20. A lot of outdoor air blown from) is mixed. As a result, since the exhaust temperature from the exhaust port 33 and the amount of water per exhaust capacity can be reduced and exhausted, condensation into the housing 17 can be suppressed.

Thereafter, as the temperature in the washing tank 20 detected by the temperature detecting unit 23 decreases, the adjusting unit 36 is controlled to increase the amount of air blown through the washing tank 20. Thereby, drying of the tableware 19 can be accelerated | stimulated and the drying time can be shortened.

Further, by providing the projections 39 in the inward direction on the upper surface of the housing 17, the contact area with the exhaust air is increased, and the temperature of the exhaust gas is further increased by the temperature difference with the upper surface of the housing 17 close to the outside air temperature. Can be reduced. In addition, when the humidity of the exhaust gas at the initial stage of the exhaust process is high and the temperature difference with the upper surface portion of the housing 17 is large, the moisture of the exhaust gas can be recovered as condensation water.

Moreover, since the recessed part 38 is provided in the upper surface of the inner cover 27, and it is comprised so that water can be stored, it condenses on the upper surface of the housing 17, and the dew condensation which collects by the projection part 39 is easy. Can be recovered. The collected condensation water can be dried during operation by the heat of the inner lid 27 which becomes a high temperature during the drying step and the exhaust gas whose humidity gradually decreases.

In addition, since the vent 41 is provided at a position lower than the exhaust port 33, the exhaust gas that passes between the housing 17 and the inner lid 27 from the exhaust port 33 collides with the rear portion of the housing 17. Thus, it is discharged from the vent 41 to the outside of the washing machine. At this time, the exhaust can be slightly condensed by heat exchange with the rear part of the housing 17, so that the exhaust can be exhausted to the outside of the cleaner in a reduced humidity. In addition, although dew condensation is dried by exhaust gas which gradually decreases in humidity, when condensation water remains due to conditions such as low outside temperature, the condensation water remains, which is collected at the bottom of the housing 17 and the like. This allows the dew condensation water to be quickly dried for easy treatment.

This allows the user to use the dishwasher with confidence without worrying about the exhaust when working in front of the dishwasher or passing in front of the dishwasher. In addition, while the dishwasher suppresses condensation in the housing 17, the condensation water can also be quickly evaporated and easily processed.

As described above, the dish washing machine of the present invention includes a housing, a washing tank, an inner lid, a blowing unit, a first blowing path, a second blowing path, and an adjusting unit. The housing has a first opening at the front. The cleaning tank is installed in the housing so as to be movable in the front-rear direction, and has a second opening upward, and has a door covering the first opening when housed in the housing. The inner cover opens and closes the second opening provided in the housing. The blowing unit blows outside air into the cleaning tank through the first blowing path, and simultaneously discharges the air in the cleaning tank from the exhaust port through the exhaust path. The second blowing path is provided branched from the first blowing path so as to mix the outside air blown by the blowing unit into the exhaust path. The adjusting unit is provided in the first blowing path to adjust the blowing amount in the cleaning tank and the second blowing path. The exhaust port is configured to exhaust in the housing.

Thereby, by not exhausting the exhaust from the front of the dishwasher, it is possible to use the dishwasher without worrying about the exhaust when the user works in front of the dishwasher or passes through the front of the dishwasher.

Further, in the dish washing machine of the present invention, the exhaust port is arranged to exhaust the gap between the inner cover and the housing.

As a result, the exhaust can be brought into contact with the upper surface of the housing to lower the temperature, and condensation to the upper surface of the housing due to the exhaust can be recovered from the upper surface of the inner lid.

Moreover, in the dish washing machine of this invention, the some inward direction protrusion part is provided in the upper surface of a housing | casing, and the recessed part is provided in the upper surface of an inner cover below the protrusion part.

As a result, the contact area with the exhaust gas can be increased to further lower the temperature of the exhaust gas. In addition, when the humidity of the exhaust gas is high, moisture of the exhaust gas can be recovered as condensation water and stored in the concave portion of the upper surface of the inner lid.

As described above, the dishwasher according to the present invention does not discharge the exhaust from the front of the dishwasher, so that it is possible to use the dishwasher without worrying about the exhaust when the user works in front of the dishwasher or passes through the front of the dishwasher. . This is useful as a dish washer of the type used in the built-in system kitchen.
