Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and particularly relates to a regional washing structure of a dishwasher. Background Art

[0002] Chinese Patent Document No. CN212939637U disclosed an inner container structure of a dishwasher on April 13, 2021. The inner container includes a chassis and a top plate covering the chassis. The chassis includes a frame with a rectangular cross-section and an opening on one side. The frame includes three side wall parts respectively connected to the top plate. A water collecting groove is provided on the chassis. A lower spray arm and a lower spray arm mounting seat are also provided on the chassis. A drainage pump, a heating device, a washing pump, and a water collecting cup communicated with the water collecting groove are provided at the bottom of the chassis. The drainage pump and the heating device are respectively connected to the water collecting cup. The washing pump is connected to the heating device. The lower spray arm mounting seat is connected to the washing pump through a pipeline. An upper spray arm and a lower spray arm are arranged inside the inner container of this dishwasher for spray cleaning tableware. The upper spray arm and the lower spray arm mainly have a circular spray trajectory and can evenly spray and wash the entire loading area. However, for the cleaning of cups, due to the small volume and relatively deep depth of the cups, it is difficult to clean the inside of the cups thoroughly only by the upper spray arm and the lower spray arm, and the cleaning effect is poor.

[0003] Therefore, it is necessary to make further improvements. Summary of the Utility Model

The first buckle position and the first buckle hole are buckled with each other to connect the spray arm and the first water inlet joint; a second buckle hole is provided on the water inlet pipe, and a second buckle position is provided on the second water inlet joint. The second buckle position and the second buckle hole are buckled with each other to connect the water inlet pipe and the second water inlet joint.

[0013] The main water inlet assembly includes a main water inlet pipe and a connecting pipe head which are integrally or separately arranged. When the spray arm water inlet assembly communicates with the main water inlet assembly, the main water inlet pipe, the connecting pipe head, and the spray arm water inlet assembly are connected in sequence. A third buckle position is provided on the connecting pipe head, and a third buckle hole is provided at the other end of the water inlet pipe. The third buckle position and the third buckle hole are buckled with each other to connect the main water inlet pipe and the water inlet pipe.

[0014] A water inlet seat for connecting the first water inlet pump is provided at the bottom of the main cleaning area, and the water inlet seat communicates with the spray arm device and the main water inlet assembly respectively.

[0015] In the present utility model, by providing a regional washing spray arm assembly on one side or both sides of the spray arm device, the regional washing spray arm assembly is rotationally limited on the main cleaning area to form a locally cleanable area with adjustable angle.
