Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a lower basket assembly and a dishwasher. Background Art
[0002] At present, most household dishwashers on the market, especially the drop-down door dishwashers, have a washing area in the inner tank that is nearly square in shape when viewed from above. The spray arm below the dishwasher rotates horizontally around its central axis to form a circular coverage area. It is difficult for the spray water column to directly reach the four corners of the washing cavity, thus forming an under-washed area. In order to solve the problem of under-washed tableware, generally one or two auxiliary spray walls are added at the corners of the washing cavity to strengthen the spraying at the corners of the washing cavity, thereby forming a high-energy washing area.
[0003] This type of dishwasher with a secondary spray arm has a better cleaning effect on tableware in the high-energy washing area. However, for the dishwasher bowl basket, the types of tableware that can be placed in each area of the bowl basket are generally fixed, so the use and placement of tableware types are also relatively fixed. The high-energy washing area can only perform strong cleaning on certain tableware in the high-level washing area. Users cannot place heavily greasy tableware in the high-energy washing area according to actual needs, and the user experience is poor.
[0004] Therefore, there is an urgent need for a bowl and basket assembly to solve the above problems. Summary of the invention
