<P>PROBLEM TO BE SOLVED: To provide a beverage supply device capable of easily detecting abnormality such as temperature rise generating in a compressor. <P>SOLUTION: This beverage supply device includes: a water storage tank; a cooling device having the compressor and cooling the water in the water storage tank; a temperature sensor detecting a temperature of the water in the water storage tank; and a determining device in which a threshold temperature is set between a first temperature region in which a lowering rate of water temperature in the water storage tank is approximately constant, and a second temperature region which is lower than the first temperature region, and in which the lowering rate of the water temperature in the water storage tank is not approximately constant, in cooling the water in the water storage tank by the cooling device, so that it is determined that the compressor is in an overload state when a lowering rate per a specific time, of a detection temperature by the temperature sensor is smaller than a first rate in a case when the detection temperature of the temperature sensor is higher than the threshold temperature, and it is determined that the compressor is in an overload state, when the control for continuously driving the compressor is continued for a specific time or more in a case when the detection temperature of the temperature sensor is lower than the threshold temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
