02 When cleaning the upper surface with water, this may be performed while sprinkling water in a shower shape. Alternatively, when performing water work in the sink cabinet 102, a relatively large amount of water may be scattered around. At the time of such water handling, much of the water spills on the lid 105 of the dishwasher 101 and the periphery thereof, and relatively to the peripheral portion A outside the packing 106 at the opening of the washing tank 104. Much water may be trapped or stored. In this case, when the lid 105 is opened, the water on the upper surface of the lid 105 and the water in the peripheral portion A may be scattered into the washing tank 104 at one time and may be caught on the tableware inside. In order to prevent this, it is necessary to make the upper end surface of the upper frame 104b higher than the surrounding portion A (need to have a bank shape). However, in this case, the lid 105 of the dishwasher 101
Becomes higher than other parts (the upper surface of the cabinet 102), and the usability is deteriorated. That is, the user often uses the upper surface of the lid 105 of the dishwasher 101 for cooking and water work, and it is inconvenient if the lid 105 is high.
