Dishwasher

Abstract

Provided is a dishwasher. Adjustment of a dish rack between a high position and a low position is completed under an action of a triggering member, an adjustment piece and an adjustment support. The adjustment support and the disk rack move synchronously, the adjustment support is connected with the triggering member, the triggering member plays a role of switching, and the adjustment piece itself is fixed. When the dish rack is located at the high position, the triggering member is propped against a limiting end of the adjustment piece; and when the dish rack needs to be lowered from the high position to the low position, the triggering member needs to rotate only. At the moment, the triggering member is departed from the limiting end.
