Coffee maker and microwave oven and method for controlling the same which can prevent electric components suffering from damage caused by overheating of a heater. <??>The coffee maker and microwave oven includes an outfit room (20) for mounting various electric parts on an inside thereof, a case (31) at one side of the outfit room (20), a water tank (32) in an upper space of the case (31), a funnel (33) under the water tank (32) having a filter for extracting coffee, a water supply pipe (36) having a first pipe (36a) connected to the water tank, and a second pipe (36b) for supplying potable water to the funnel (33) directly, a water supply tube (37) on a bottom of the case (31), having one end connected to the first pipe (36a), and the other end connected to the second pipe (36b), a heater tube (35) in contact with the water supply tube (37), the heater tube (35) having a heater (35a) for heating potable water passing through the water tube (37), and a temperature sensing unit (100) in the vicinity of the heater tube (35) for measuring a temperature of the heater (35a). <??>The method includes the steps of a user putting a coffee maker unit into operation, supplying potable water from a water tank (32) to a funnel (33) through a water pipe (36) and a water tube (37), and, at the same time with this, putting a heater (35a) in a heater tube (35) in contact with the water tube (37) into operation, to heat the potable water passing through the water tube (37), measuring a temperature of the heater periodically by using a temperature sensing unit (100) in the vicinity of the heater tube (35), calculating a rate of temperature change of the heater (35a) according to the temperature measured, and cutting off power supply to the heater (35a) if the rate of the temperature change of the heater (35a) is higher than a preset value. <IMAGE> |
