Abstract: An automatic water supply device comprises a pot-shaped case having a space enclosing a flowerpot in the inside, a supporting bed of reverse bowl shape enclosed in the case and holding the flowerpot thereon, a control unit arranged in a gap between the inside of the case and the flowerpot and containing at least an air pump, a controller and a timer, an air tube connected to outlet side of the air pump and having a front end part communicating with the inside of the supporting bed, and a device to exhaust air in the supporting bed when the supplying water is finished. Since the water supplying device basically has simple structure that a supporting bed of reverse bowl shape is inserted from the upper side and enclosed in the case, a part storing water can be taken to pieces and inspection or cleaning is easy.
