Sump for dishwasher

Abstract

A sump for a dishwasher includes a sump case for storing washing fluid, a washing pump assembly including a flow guide to pump out the washing fluid, and a filtering assembly including a flow guide to accumulate foreign particles contained in the washing fluid during the circulation of the washing fluid. The sump includes a sump cover to cover an opening of the sump case, and a self-cleaning assembly for filtering out the foreign particles directed to the flow guide. The flow guide, the sump cover and the self-cleaning assembly are thermally bonded to form a single unit.

Description

technical field [0001] The present invention relates to a dishwasher, in particular to a storage tank for storing washing water and pumping out the stored washing water by using high pressure. Background technique [0002] Generally speaking, a dishwasher is a machine that washes and dries dishes by spraying high-pressure washing water onto the upper and lower dish racks. The dishwasher includes a tub, a dish rack for placing dishes, a spray head for spraying washing water onto surfaces of the dishes, and a sump installed at the bottom of the tub for storing the washing water. [0003] In addition, in a conventional dishwasher, a debris collection filter for collecting food residues generated during washing is installed in a sump. Alternatively, the debris is ground into particles so that it can be discharged together with the used wash water during discharge. [0004] The sump includes a sump housing for storing washing water, a sump cover covering the sump housing, a fil...

Problems solved by technology

Therefore, an increase in manufacturing cost due to an increase in the number of joints

Additionally, leaks may occur between assembled components

[0007] 2. In the process of supplying washing water from the washing pump to the water guide connecting the upper and lower nozzles, the flow resistance will increase

[0008] 3. Since the washing pump and the sundries collecting space are arranged in a single part, sundries may enter the washing pump through the boundary between the sundries collecting space and the washing pump, and thus sundries may be sprayed through the nozzle together with the washing water out

[0010] During the wash water pumping process, the wash water may leak from the wash pump
