Description

Dishwasher rack and dishwasher

technical field

The invention belongs to the technical field of home appliances, and in particular relates to a rack for a dishwasher, and also a dishwasher with the rack.

Background technique

At present, most dishwashers use the rotation of the spray structure to wash the tableware. The water flow sprayed by the spray structure can cover most of the racks in the dishwasher, so as to wash the tableware in the racks. However, Because the distribution of water flow in this washing method is relatively scattered, for deep tableware, such as cups, water bottles, etc., the water flow less touches the bottom of the tableware, even if the water flow can be washed to the bottom of the tableware, it will be due to the long spray distance and insufficient flushing force. This makes the washing effect poor; some dishwashers use a spray structure under the deeper cup, but because the water sprayed by it is still far from the bottom of the tableware, it cannot achieve the purpose of strengthening washing, and only increases the amount of washing. times, resulting in waste of water resources.

The present invention has been made in view of this.
