PROBLEM TO BE SOLVED: To provide a water supply device for suppressing the temperature rise of a control board due to the heat of the control board itself housed in a small housing space in parallel to a motor as well as heat given from the motor. SOLUTION: The water supply device comprises a shielding member 57 having a passage portion 58 for shielding between a water supply pump 11a and the control board 60 neighboring each other, whereby an air around the control board 60 can flow while shielding the control board 60 from motor exhaust heat. A partition plate 57 allows the control board 60 to be not only shut off from the heat of a motor 12 itself and further off from blasts passing through the outer face of a body of the motor 12 but also positively cooled by an air flowing therearound. Therefore, the thermal influence of the control board 60 is avoided and the excessive temperature rise of the control board 60 is prevented.
