Dish washing machine

Abstract

Disclosed herein is a dish washing machine including a sump unit capable of reducing the number of elements thereof, and minimizing the number of coupling portions of the elements. The dish washing machine includes a washing tub, a sump unit arranged in the washing tub, and at least one injection nozzle to inject wash water into the washing tub. The sump unit includes a sump housing, an impeller to pump wash water from the sump housing, a guide member, to which the sump housing is mounted, the guide member guiding the wash water pumped by the impeller directly to the at least one injection nozzle, and a housing cover to cover the sump housing and the guide member. The housing cover is formed with a garbage chamber to collect garbage contained in the wash water.

AI Technical Summary

Benefits of technology

[0011]It is an aspect of exemplary embodiments to provide a dish washing machine including a sump unit capable of reducing the number of elements thereof, and minimizing the number of coupling portions of the elements.

[0012]It is another aspect of exemplary embodiments to provide a dish washing machine including a sump unit having a simple inner channel structure.

[0014]It is a further aspect of exemplary embodiments is to provide a dish washing machine including a sump unit having a structure capable of easily removing garbage, etc. fixed to a garbage chamber.

Problems solved by technology

However, a complicated assembly process may be required because a large number of constituent elements are assembled.

Also, an increase in manufacturing costs may occur due to an increased number of elements to be assembled and an increased number of assembly processes.

Since a large number of constituent elements are coupled in a stacked state, the structure of inner channels defined in the sump unit is complicated.

The increased number of elements may cause an increase in the volume of the sump unit.
