When an operator uses the dishwasher, the dishwasher is first lightly washed in the counter sink. Next, the door of the dishwasher is opened so that it is tilted forward, and usually the upper net is pulled out first. Since the upper screen has a structure supported by rails, it mainly stores small dishes in the pulled out state and pushes them back into the dishwasher cabinet.
The lower screen has a structure with a caster at the bottom, and can be pulled out from the cabinet onto the back of the door. And an operator moves cooking utensils, such as tableware and a pot pot which are heavy, into the lower net of the bottom from a sink, and pushes it in a dishwasher cabinet again.
Finally, after the door is rotated and closed, the switch is turned on for operation. Specifically, cleaning is performed by jetting while rotating warm water together with the detergent, and when rinsing is completed, the temperature in the cleaning / drying chamber is raised by a heater, and drying is performed while discharging moisture.

The dishwasher / dryer built-in from the front has the following problems in terms of use and the structure of the equipment.
When the lower net is pulled out, the position of the net is far from the sink and the height is extremely low, such as the knee of the operator. It was scattered on the counter and the floor, and the movement of bending and twisting the knees and hips was repeated, which made it difficult to transfer the dishes and caused fatigue. In addition, since the same operation | movement was reverse also when taking out tableware after drying, there existed the same problem.
In the structure in which an opening is provided on the upper side of the dishwasher / dryer on the side of the counter sink described above, workability is impaired because the area of the counter that can be freely used is reduced. In addition, it is necessary to process the counter at the time of manufacture, and its installation becomes a narrow place in the cabinet, so that workability is poor and has become a problem.
For this reason, in the dishwasher that is built-in from the front as in the present invention, a mechanism for raising and lowering the lower mesh basket has been vaguely demanded, but from the standpoint of simplicity of the mechanism, ease of use, production cost, etc. No realistic technical proposal that could be commercialized has been made.
