Description

[Technical field]

[0002] The present invention relates to household appliances, in particular to household cleaning water washing appliances. [Background technology]

[0004] Generally, a dishwasher washes the dishes by spraying high-pressure washing water onto the dishes, and dries the dishes after washing is completed.

[0005] Generally, a dishwasher includes a housing in which a washing space is provided, a cutlery basket, and a spray unit that sprays high-pressure washing water toward cutlery placed in the cutlery basket.

[0006] In the traditional dishwasher setting, a spray unit is set at the top of the washing space. The structure is disclosed in the patent No. 200710307181.2, entitled Water-using Household Appliance with Device for Dispensing Detergent. Later, in order to prevent the occurrence of blind spots in washing, it was proposed to change the spray unit to a rotatable structure, or to change the cutlery basket to a displaceable structure, in an effort to wash the cutlery on the cutlery basket more thoroughly. The spray trajectories of the above two spray units are fixed, which can be called a single fixed trajectory structure. Since the cutlery on the cutlery basket is placed closely together, the washing effect of the single fixed spray trajectory is not ideal, especially for the cutlery with a deeper depth, the washing effect is even worse, and the washing blind spot is difficult to avoid.
