<P>PROBLEM TO BE SOLVED: To provide a water supplying device provided with a cooling mechanism which has a simple structure and low noise, allows the water supplying device to be downsized, and efficiently and accurately cools heating body components such as an inverter element. <P>SOLUTION: The water supplying device 1 is provided with: a pump 10; a delivery pipe arrangement 20 connected to a delivery opening 11b of the pump 10; a motor 30 driving the pump 10; and an inverter device 40 supplying electric power to the motor 30, and is also provided with the cooling mechanism which cools heating body components such as the motor 30 and the inverter device 40. The cooling mechanism is provided with a heat transfer plate 6 connecting the inverter device 40 and the delivery pipe arrangement 20, water cooling of the inverter element mounted in the inverter device 40 is carried out by delivery water in the delivery pipe arrangement 20 via the heat transfer plate 6, air in the water supplying device 1 is cooled by the heat transfer plate 6 by exposing at least one part of the heat transfer plate 6 into a space in the water supplying device 1, and temperature rising of the motor 30 and the inverter device 40 is suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
