  And the exhaust port 17 and the exhaust path 16 located in the upper part of the decorative panel 9a in the vicinity of the exhaust port 17 are constituted by the upper end surface 9d of the decorative panel 9a at the part that becomes the long side of the lower part in the lateral direction. Yes. That is, the upper long surface 16a that is long in the horizontal direction and the left and right short surfaces 16b that are short in the vertical direction are integrally formed with the other portions as the exhaust passage 16, and the lower ends of the left and right short surfaces 16b are the upper portion of the decorative panel 9a. An elongated rectangular exhaust port 17 is formed by contacting the end surface 9d. Further, at an appropriate position of the exhaust port 17, at least one rib 16c is formed in parallel with the short surface 16b so as to contact the upper end surface 9d of the decorative panel 9a. And the upper end surface 9d of the decorative panel 9a abuts the lower end of the left and right short surfaces 16b and the ribs 16c when the decorative panel 9a is fixed to the support portion 9c, and regulates the position in the upward direction.

  Further, a temperature sensor 21 is provided outside the bottom surface of the cleaning tank 2. The control device 11 detects the ambient temperature immediately after the operation without the cleaning water in the cleaning tank 2 by the temperature sensor 21, detects the temperature of the cleaning water in the washing step and the rinsing step after the cleaning water is supplied, and the drying step. Then, the temperature of the air in the washing tank 2 is detected. The control device 11 controls a washing step, a rinsing step, and a drying step according to a signal from the temperature sensor 21 and executes a washing operation. Further, the control device 11 controls the operation time of the first blower 13 and the second blower 19. And if it enters into a drying step, according to the atmospheric temperature detected immediately after the operation start, the combination of the operation time of the 1st air blower 13 and the 2nd air blower 19 will be controlled, and the high temperature high from the washing tank 2 will be controlled. Adjust the mixing ratio of humid air and external air. As a result, the temperature and humidity of the air exhausted from the exhaust port 17 are lowered to prevent dew condensation to the surroundings and not to make the user uncomfortable.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The user grasps the handle 9 b provided on the door 9 and pulls out the washing tub 2 from the housing 1, and places the dirty tableware 4 in the tableware basket 5 arranged in the washing tub 2. Next, a detergent is put in, a driving course is selected by a course selection button in the operation unit 12, and a driving start button is pushed. Then, the cleaning tank 2 is pushed into the housing position in the housing 1. At this time, the inner lid 10 is moved backward and downward by the link mechanism 10b to close the opening of the cleaning tank 2. At the same time, the micro switch (not shown) detects that the cleaning tank 2 is in the fully pushed position, and sends a detection signal to the control device 11, and the control device 11 starts the cleaning operation.

  When the cleaning operation is started, the control device 11 opens a water supply valve (not shown) and supplies tap water serving as cleaning water. Further, while washing water is heated by the heater 8 disposed in the washing tank 2, a washing step is performed in which the washing nozzle 7 sprays the dishes 4 toward the dishes 4 to remove stains on the dishes 4. Then, after rinsing by changing the washing water a plurality of times as a rinsing step, a rinsing heating rinsing step is performed while heating the newly supplied washing water to about 80 ° C. by the heater 8. Thereafter, the cleaning water is drained, and the air in the cleaning tank 2 is heated by the heater 8, and the high-temperature air containing a large amount of moisture is discharged from the discharge hole 15 by the first blower 13, and the dishes 4 and the cleaning tank A drying step for drying the inside of 2 is performed, and the operation is terminated by reaching a predetermined time or a predetermined temperature.

  Usually, the gap between the kitchen counter 20 and the upper end of the door 9 is as narrow as several millimeters. When the exhaust path 16 and the exhaust port 17 are provided in the narrow gap to exhaust the air outside the machine, the height of the exhaust port 17 becomes very small. In particular, if the upper long surface 16a of the exhaust path 16 and the lower long surface facing the long surface 16a are configured as gaps using respective members, the height of the exhaust port 17 becomes extremely small, and the cleaning tank There is a possibility that the air in 2 is not sufficiently exhausted and the drying performance is deteriorated. On the other hand, if the portion corresponding to the lower long surface of the exhaust path 16 is configured by the upper end surface 9d of the decorative panel 9a as in the present embodiment, the areas of the exhaust path 16 and the exhaust port 17 are maximized. Therefore, it is possible to secure a necessary air volume and prevent a decrease in drying performance.

  In addition, since the exhaust port 17 is disposed behind the front surface of the decorative panel 9a, it is difficult for the user to see the dishwasher in the state where it is stored in the system kitchen K, and in particular, it cannot be seen when standing near the kitchen counter 20. The design of the system kitchen K in which the dishwasher with the design of the door 9 is accommodated is not impaired.

  The decorative panel 9 a attached to the door 9 is finely adjusted according to the vertical position of the door or drawer of the system kitchen K adjacent to the door 9. Therefore, the exhaust port 17 may be blocked by the decorative panel 9a and the exhaust may be hindered. However, according to the present embodiment, the mounting position in the upward direction is regulated by the short surface 16b and the lower end of the rib 16c. Therefore, exhaust from the exhaust port 17 is not hindered. Furthermore, when the decorative panel 9a is fixed to the support portion 9c of the door 9, the workability can be improved because the decorative panel 9a can be positioned in accordance with the short surfaces 16b and the lower ends of the ribs 16c. At this time, the fine adjustment of the vertical position of the decorative panel 9a with respect to the door and drawer of the system kitchen K is performed by extending and contracting the vertical direction portion of the exhaust passage 16 within a range in which the exhaust port 17 in the gap does not hinder the removal and insertion of the cleaning tank 2. Alternatively, the exhaust port 17 may be fixed and extended by extending and contracting the legs 22 provided on the lower surface of the housing 1.

In addition, in this Embodiment, although the exhaust port 17 is provided in the upper end surface 9d of the decorative panel 9a, and it is set as the structure arrange | positioned in the clearance gap between the decorative panel 9a and the kitchen counter 20, it does not restrict to this. For example, the exhaust port 17 is provided along either the left or right end face outside of the decorative panel 9a and is disposed in the left-right gap between the decorative panel 9a and the door of the system kitchen K, or on the lower end face of the decorative panel 9a. It is good also as a structure provided. And you may make it the exhaust port 17 regulate the attachment position of the decorative panel 9a with respect to each direction.

  In the present embodiment, one long surface of the exhaust path 16 in the vicinity of the exhaust port 17 is configured by the upper end surface 9d of the decorative panel 9a, but the size of the exhaust port 17 that does not hinder the exhaust is large. If it is obtained, the entire surrounding surface forming the exhaust path 16 may be composed of the respective members without using the end face of the decorative panel 9a. Further, the cross section of the exhaust path 16 and the exhaust port 17 are not limited to a rectangle, and may be a combination of rectangles or may have a curved surface portion.

  Further, in the initial stage of the drying step, high-temperature air that is heated and contains a particularly large amount of water is discharged from the discharge hole 15, so if it is directly discharged from the exhaust port 17, it is exhausted into the gap between the decorative panel 9 a and the kitchen counter 20. Condensation tends to condense around the exhaust port 17. In order to prevent the dew condensation, the control device 11 intermittently operates the first blower 13 that discharges high-temperature air containing moisture to reduce the air volume and mix the air outside the cleaning tank 2. By continuously operating the device 19 and increasing the air volume, the temperature and humidity of the exhaust gas in which these airs are mixed can be lowered, and the surrounding dew condensation can be prevented. The air volume change of each blower may be time adjustment by intermittent operation or rotation speed adjustment by continuous operation.

  At this time, when the ambient temperature is low, the surface temperature of the decorative panel 9a and the kitchen counter 20 is also low, so the dew point temperature is low and condensation is likely to occur. Therefore, the control device 11 is changed so as to suppress the operation time of the intermittent operation of the first blower 13 to reduce the discharge amount of the high-temperature air from the washing tank 2, and the washing tank 2 by the second blower 19. While reducing the ratio to the air volume from the outside, the operation time of the drying step is extended in order to maintain the drying performance. In this way, the control device 11 estimates the surface temperature of the decorative panel 9a and the kitchen counter 20 by detecting the ambient temperature at the start of operation by the temperature sensor 21, and if the ambient temperature is high, the first is more than necessary. Without suppressing the operation of the air blower 13, the drying step is efficiently performed for a short time while preventing dew condensation to the surroundings. If the ambient temperature is low, dew condensation to the surroundings can be achieved even if the drying step time is extended. Suppress. Thereby, the optimal drying operation according to atmospheric temperature can be performed.

  The dishwasher of the present embodiment includes a first blower 13 that blows air to the washing tub 2 and a second blower 19 that joins air outside the washing tub 2 in the middle of the exhaust path 16. However, it is not limited to this. For example, the flow dividing device (not shown) which does not have the 2nd air blower 19, and diverts the ventilation by the 1st air blower 13 into the flow path which flows in into the washing tank 2, and the air flow path 18 which does not flow in instead. And the air that has flowed into and discharged from the cleaning tank 2 and the air from the blower path 18 are merged in the middle of the exhaust path 16. You may adjust the ratio with the air volume from the tank exterior.

  As described above, the dishwasher according to the present invention comprises a decorative panel and a kitchen counter by forming a part of the exhaust path to the exhaust port provided at the top of the decorative panel and having an opening in the front on the upper surface of the decorative panel. When exhausting from the gap, the area of the exhaust port can be enlarged and the drying performance can be improved, so the decorative panel of the same material and size as the door of the system kitchen to be stored was applied to all the front A dishwasher with excellent design can be provided.
