Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a sink-type washing machine for washing tableware, fruits and vegetables. Background Art

[0002] The sink-type cleaning machine uses a sink to define a washing chamber and adopts an upward-flipping door structure.

[0003] For example, the applicant's prior patent ZL 202321042974.7 "A water tank cleaning machine" discloses a structure, which includes a water tank with a receiving cavity and a top opening connected to the receiving cavity; a spray arm, which is arranged in the receiving cavity of the water tank and connected to the first water supply channel; and a door body is arranged on the top of the water tank. The above structure is a common structure of a water tank cleaning machine.

[0004] A sink-type washing machine usually places a layer of bowl baskets near the bottom in the washing chamber, and a spray arm is set at the bottom of the bowl basket and sprays upward to rinse the dishes in the bowl basket. The above structure makes it impossible to effectively utilize the space above the washing chamber, and the number of dishes washed is restricted. If another layer of bowl baskets is set on top of the bottom bowl basket, the water column sprayed by the spray arm sprays from bottom to top, the spray direction is relatively fixed, and the spray coverage area is limited. The upper bowl basket is prone to have a dead corner for cleaning, making it difficult to achieve thorough cleaning. Utility Model Content
