  However, in such a conventional configuration, it is difficult to determine the state inside the cleaning tank when the door is closed, and it is necessary to indicate whether the operation process is cleaning or rinsing by some method. There wasn't. Moreover, since it is necessary to check whether the tableware in washing | cleaning is fully wash | cleaned, it is necessary to pause in the middle of a driving | running | working and open a door body, it was a very troublesome operation | work.

  In addition, it is conceivable to configure a transparent or semi-transparent part in the door body so that the inside can be seen, but with such a construction, the inside can be seen more than necessary, during the first cleaning process. In addition, there was a problem that unpleasant sensation was given because even a very dirty washing water in which a large amount of tableware was dissolved was circulated. Moreover, if it is made semi-transparent in order to make contaminated water difficult to see, it will become difficult to see the inside of the target.

  Therefore, it is conceivable to illuminate the interior with a lighting device so that the interior can be seen when necessary. In this case, there is no problem locally, but the inside of the washing tank can be seen as wide as possible. In order to achieve this, it is necessary to enlarge the transparent part or the semi-transparent part. When the lamp is irradiated in a direction substantially perpendicular to the transparent part or the semi-transparent part, a plurality of lamps are arranged so that the entire visible part is illuminated. Since it is necessary to install it in different places or a large lamp that can irradiate the whole place in one place, it has a problem that the cost is increased and the running cost is increased accordingly.

  The present invention solves the above-described conventional problems, efficiently illuminates the visible portion in the cleaning tank from the transparent or translucent portion with a small light source, reduces the cost of the lighting device, and illuminates the lighting device. The purpose is to reduce the amount of power to be generated.

Yes. Both the upper door body 11 and the lower door body 12 have a horizontally long substantially rectangular shape, and the upper door body 11 has a transparent portion or a semi-transparent portion 15 that allows the inside of the cleaning tank 9 to be visually recognized. is doing.

  Further, an illumination device 17 that illuminates the inside of the cleaning tank 9 is disposed on the upper surface 16 near the side surface of the cleaning tank 9. The illuminating device 17 is provided with a hole in a part of the upper surface 16 of the cleaning tank 9, and has a transparent cover part 18 projecting into the cleaning tank 9 downward from the upper surface and a lamp 19 serving as a light source. The lamp 19 is a transparent cover part. 18 is substantially parallel to the transparent part or translucent part 15 from the position protruding into the washing tank 9 through, i.e., the longitudinal direction of the transparent part or translucent part 15. It is configured to irradiate.

  Further, the lighting device 17 is configured so as to irradiate the lamp 19 at the same time only when the atomizing device 14 is in operation in conjunction with the power source of the atomizing device 14.

  In the above configuration, the operation and action will be described. The user opens the door bodies (upper door body 11 and lower door body 12), and the dish basket placed in the washing tub 9 in the dishwasher body 7 becomes dirty. Set tableware 8

  Next, when the detergent is put into the atomizer 14, the door bodies (the upper door body 11 and the lower door body 12) are closed and the operation is started, the cleaning water containing the detergent is first atomized by the atomizer 14. In the atomization process, the detergent solution is attached to the tableware 8 to raise the dirt from the tableware 8, and after the process, the cleaning water is heated by a heater (not shown) arranged at the bottom of the cleaning tank 9. However, a cleaning process is performed in which cleaning water is sprayed from the cleaning nozzle 13 toward the tableware 8 to wash away the stains on the tableware 8. Thereafter, the tableware 8 is rinsed, and then the drying process is performed to finish the operation.

  In this atomization process, the lamp 19 of the illuminating device 17 is lit to irradiate the tableware 8 in accordance with the operation of the atomizing device 14. At this time, the light from the lamp 19 of the illuminating device 17 is configured to irradiate from the vicinity of the side surface of the cleaning tank 9 to the horizontally long, substantially rectangular transparent portion or semitransparent portion 15 provided in the upper door body 11 in a substantially parallel manner. Therefore, it is possible to illuminate the horizontally or horizontally end of the transparent portion or translucent portion 15. Therefore, the visible part in the washing tank 9 from the transparent part or the semi-transparent part 15 is efficiently illuminated with only one small light source, the cost of the illumination device 17 is reduced, and the lamp 19 and thus the illumination device 17 irradiates. The amount of power can be reduced.

  In the present embodiment, the transparent portion or translucent portion 15 of the upper door body 11 is a horizontally long substantially rectangular shape. However, when the vertically long substantially rectangular shape is used, the lamp is also irradiated substantially parallel to the vertical direction. A similar effect can be obtained. Moreover, since the inside of the cleaning tank 9 is illuminated by the lighting device 17, it is possible to easily confirm the state of the mist of the cleaning liquid that is difficult to see if it is translucent.

  Even in the case of complete transparency, since the inside of the cleaning tank 9 becomes difficult to be seen by reflection of light from the outside by the transparent part or the semi-transparent part 15, the inside of the cleaning tank 9 is illuminated by the illumination device 17, so that The effect is obtained.

  Moreover, since the illuminating device 17 is arrange | positioned with respect to the atomization apparatus 14 arrange | positioned at the bottom part of the washing tank 9 on the upper surface of the washing tank 9, the mist of the cleaning liquid by the atomization apparatus 14 starts from the bottom part in the washing tank 9. The state of rising and filling the cleaning tank 9 can be made easier to see.

  Moreover, since the illuminating device 17 is configured to turn on only the atomization process, the illuminating device 17 is unexpectedly activated during the cleaning process, and very dirty washing water in which a large amount of contamination of the tableware 8 is melted can be seen. An unpleasant feeling can be prevented. It should be noted that if the lighting device 17 is turned on or off, it is easier to use if a switch is added so that the user can easily change the lighting.

  Thus, according to the present embodiment, the cleaning tank having an opening on the front surface, a door body that opens and closes the opening, and a lighting device that is provided in the cleaning tank and illuminates the inside of the cleaning tank, A transparent part or a semi-transparent part that allows the inside of the cleaning tank to be visually recognized is provided in a part of the door body, and the lighting device is configured to emit light substantially parallel to the transparent part or the semi-transparent part. By this, the visible part in the washing tank from the transparent part or the semi-transparent part can be efficiently illuminated with a small number of light sources, the cost of the lighting device can be reduced, and the amount of power irradiated by the lighting device can be reduced.

  Further, since the illumination device is disposed on the side surface of the cleaning tank or in the vicinity of the side surface, the lamp can irradiate the transparent portion or the semi-transparent portion substantially in parallel.

  Further, by arranging an atomizing device for atomizing the detergent liquid at the bottom of the cleaning tank, it is possible to easily confirm the state of the fog of the cleaning liquid that is not transparent even if it is translucent.

  Further, since the lighting device is disposed above the atomizing device, it is possible to make it easier to see how the mist of the cleaning liquid from the atomizing device rises from the bottom of the cleaning tank and fills the cleaning tank.

  In addition, the lighting device can be turned on only while the atomizing device is in operation, so that the very dirty washing water in which a large amount of tableware is dissolved can be seen during the washing process performed after the atomizing process. Giving can be prevented.

  As described above, the dishwasher according to the present invention efficiently illuminates the visible part in the washing tank from the transparent part or the translucent part with a small light source, and the state inside the washing tank becomes visible when necessary. It is useful as a dishwasher or the like in which a transparent part or a semi-transparent part is provided in a part of the door body so that the inside of the washing tank can be visually recognized.
