Description

Dish washing machine

The application is a divisional case with application date of ' 2014-06-18 ', application number of ' 2014102740509 ' and application name of ' dishwasher

Technical Field

The invention relates to the technical field of household appliance manufacturing, in particular to a dish-washing machine.

Background

The water used in each washing cycle of the dish-washing machine is circulating water, and a water cup used for storing water and placing a filter screen is generally arranged at the bottom of an inner container of the dish-washing machine. In the washing process, circulating water in the water cup is pressed into a pipeline through a washing pump suction pump and then enters a sprayer (such as a spray arm) to wash tableware, and the circulating water flows into the bottom from the tableware and the inner wall of the inner container and then enters the water cup. In order to achieve a better washing effect, the washing pump must have sufficient lift and flow, and meanwhile, a heating pipe is required to be arranged in a path where circulating water flows for heating the circulating water and then washing the circulating water. In order to meet the target requirements of low energy consumption and low water consumption of the whole dishwasher, the requirement design of a water flow system is compact, and the occupied volume of a circulating water path is small; meanwhile, the pumped water path is required to be smooth, the pressure loss is small, and the washing water pump is high in efficiency.

In the related technology, a water cup of the dish washing machine is connected with an inner container through a connecting piece nut and a sealing ring. The spray arm seat is fastened on the water cup through screws. The water cup is provided with a washing pump, a heating pipe cavity, a buckle screw and other connecting features, and the washing pump assembly, the heating pipe assembly and the draining pump are connected together. A filter system assembly is arranged in the water cup, and the components are combined to form a complete water flow system. Because the water cup and the inner container need to be connected through the nut and the sealing structure, the whole water leakage risk points are more, the cavity of the heating pipe on the water cup is large, and water pumped out by the washing pump enters the spray arm seat through 360-degree folding. The existing system has the defects of more assembly parts, complex assembly and more water leakage points; too long water flow pipeline, more residual water, large pressure loss of the washing pump and other system defects. Meanwhile, the washing pump is rigidly connected with the water cup, and the vibration of the washing pump is directly transmitted to the bottom plate of the inner container, so that the noise of the whole machine is larger, and the water flow system is obviously insufficient in the aspect of realizing the low-noise technology of the whole machine.
