2. Description of the Related Art A washing tank of a drawer type dishwasher slides between a withdrawn position withdrawn from the washer body and an accommodated position with which it is accommodated. The dishes are stored in the washing tank in a state of being pulled out from the main body of the washing machine, and when the washing tank is returned to the storage position, the drawer type dish washing machine is operated to wash the dishes. A technique for sliding the cleaning tank between the drawn position and the housed position is described in, for example, Japanese Patent Application Laid-Open No. 2001-61746. As described in this publication, in a conventional drawer-type dishwasher, a rail pair including a main body side rail attached to the main body of the washing machine and a wash tank side rail attached to the wash tank moves the wash tank back and forth. Slide in the direction. The rail pair is provided on the side surface of the cleaning tank.

[0003]

When the washing tank of the drawer type dishwasher is returned to the storage position, the opening / closing lid is lowered to cover the upper opening of the washing tank. When the drawer type dishwasher is operated in this state, the washing water is vigorously ejected into the washing tank and adheres to the lower surface of the opening / closing lid and the periphery of the upper opening of the washing tank. When the drawer type dishwasher is operated in the normal operation mode, since the drying operation is performed after cleaning, the cleaning water attached to the lower surface of the opening / closing lid or the periphery of the upper opening of the cleaning tank evaporates. But as is often the case
When the drawer type dishwasher is temporarily stopped while adding dishes to the washing tank, or when operating in an operation mode in which the drying operation is omitted, the washing water is not evaporated, The cleaning water remains attached to the periphery of the upper opening of the cleaning tank. When the cleaning tank is pulled out in this state, the cleaning water falls outside the cleaning tank. As described above, since the rail pair of the conventional drawer type dishwasher is provided on the side surface of the cleaning tank, the cleaning water dropped from the peripheral edge of the upper opening of the cleaning tank falls on the rail pair. If the wash water falls on the pair of rails, the pair of rails will be corroded and the sliding will not be performed smoothly. That is, the durability of the drawer type dishwasher deteriorates.

The present invention has been made to solve the above problems, and an object thereof is to improve the durability of a drawer type dishwasher.
