A method for extracting gases dissolved in the cleaning solution of clothes or dish washing machines with recirculating circuits has a pump with a heating element within the housing and a gas ventilation valve

摘要

The performance of domestic clothes and dish washing appliances having a liquid recirculation system is reduced by foam due to dissolved air in the wash solutions which is removed by a recirculation pump (12) with a heating element (3) within the housing (14) by which the dissolved air is extracted and contained in the housing until the pump is stopped and a valve (21) opened to release the gas by a control unit (17).
