WASTE-HEAT WITHDRAWAL EQUIPMENT OF DISH WASHER AND CONTROL A METHOD FOR THE SAME

摘要

PURPOSE: A waste-heat collecting device of a dish washer and a control method thereof are provided to achieve high efficiency with little energy using a heat pump device comprising a condenser and an evaporator. CONSTITUTION: A waste-heat collecting device(100) of a dish washer(60) comprises a heat exchanger(10), a heat pump device(20), and a heater(50). The heat exchanger heat-exchanges waste-water of a high temperature discharged from the dish washer with water incoming from outside. The water heat-exchanged through the heat exchanger is transferred through a pipe and is heat-exchanged in the heat pump device. The waste-water heat-exchanged in the heat exchanger is transferred through the pipe and is heat-exchanged in the heat pump device. The water heat-exchanged in the heat pump system flows into the heater through the pipe and the heater changes the flowed-in water to rinsing water of a high temperature. The heater transfers the rinse water of a high temperature to the rinsing chamber of the dish washer through the pipe.
