  • Patent number: 11805963
    Abstract: A dish washing machine including a housing having an interior wash space for washing dishes. The housing has a liquid inlet for adding a liquid to the dish washing machine. At least one rotating spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one rotating spray nozzle for spraying onto the dishes in the interior wash space. Two heat exchange systems are within the housing. The two heat exchange systems transfer heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet. A first one of the two heat exchange systems passes heat from water in the wash tank or the interior wash space to water in the first one of the two heat exchange systems.
