Disclosed is a dishwasher that sprays washing water and steam to wash dishes or cooking appliances. The dishwasher according to the present invention includes: a tub which receives a target of washing; a sump which is disposed at a bottom of the tub to store washing water; a spray arm which sprays the washing water stored in the sump into the tub; a heater which generates heat by heating washing water in a circulation passage connecting the sump and the spray arm; and a steam passage which is connected to the steam nozzle, and in which the steam generated by the heater flows. Accordingly, the steam generated in the circulation passage may be supplied smoothly.

A pump (8) is disclosed. The pump (8) includes a partition wall (84) configured to divide the interior of a body into two spaces, a first chamber (C1) located under the partition wall (84), the first chamber (C1) having an introduction portion (841), through which water is introduced, a second chamber (C2) located above the partition wall (84), the second chamber (C2) having a discharge portion (849), through which water is discharged, a communication hole (86) formed through the partition wall (84) to allow the first chamber (C1) and the second chamber (C2) to communicate with each other therethrough, an impeller (85) provided in the second chamber (C2) to move water to the discharge portion (849), a housing configured to define the bottom surface of the first chamber (C1), the housing being made of a conductor, a heater (H) configured to heat the housing (81), and a steam discharge (843) port formed through the first chamber (C1) to allow steam to be discharged therethrough.

A pump sends washing water and generates steam in order to wash the dishes or the cooking utensils, and a dishwasher including the same. The pump includes a housing, an impeller disposed inside the housing and configured to flow washing water, and a heater coupled to a lower side of the housing and configured to generate steam by heating the washing water in the housing. The housing includes a pump lower portion configured to receive the washing water based on rotation of the impeller, and a pump upper portion configured to discharge the washing water based on rotation of the impeller and to discharge the steam generated by the heater.

A fluid flow structure for a washing machine is located within a wash tank of the washing machine, which includes a fluid flow guide surface, and a support for the guide surface. The guide surface includes at least one region contoured inconsistently from the contour of at least one corresponding wall of the washing machine wash tank. The contour of the guide surface is generally curved so as to aide in reducing and/or preventing the pinning of items that often occurs in rectangular wash tanks of the prior art. The support for the guide surface creates a gap between the guide surface and at least one wall of the washing machine wash tank.
