A container is attached to the shallow bowl at a point opposite to the weighted area and in a position to receive water from the overflow channel whereby water entering the overflow channel will be directed into the container so as to over balance the weighted area of the shallow bowl and cause the same to tip and discharge the contents thereof. Drain means in the container acts to empty the same whereby the shallow bowl returns to horizontal,normal position.
