Máquina lavavajillas doméstica con disposición de bomba de calor

A domestic dishwashing machine with a housing space (1) for accommodating washing articles (2) is proposed, where the domestic dishwashing machine comprises a heat pump arrangement with at least one evaporator (3) for evaporating a refrigerant (11) and with a condenser (5) for condensing the refrigerant (11), wherein the evaporator (3) and/or the condenser (5) comprise one or more heat exchanging elements (6) at least in sections. The domestic dishwashing machine is characterized in that at least one of the heat exchange elements (6) comprises two surface elements (7) which are joined at points through junction points (26), where the surface elements (7) and the junction points (26) delimit a free space (10) through which the coolant (11) can pass through the heat exchanger element (6), where the junction points (26) are arranged in such a way that the coolant (11) is diverted several times as it passes through the heat exchanger element (6), thus being intermixed.
